With potassium tert-butylate; In ISOPROPYLAMIDE; at 80℃; | Example A16 A solution of <strong>[84478-72-8]5-amino-2-chloro-4-fluorophenol</strong> (100 mg, 0.619 mmol) in degassed dimethylacetamide (2 mL) was treated with potassium t-butoxide (83 mg, 0.743 mmol) and 5-chloro-2-cyanopyridine (86 mg, 0.619 mmol). The resultant mixture was heated to 80 C. overnight, then cooled to RT and diluted with water (10 mL). The mixture was extracted with EtOAc (30 mL). The organic phase was washed with water (3*30 mL) and brine (30 mL) dried (Na2SO4) and concentrated in vacuo to provide 5-(5-amino-2-chloro-4-fluorophenoxy)picolinonitrile as a dark oil which was used without further purification. MS (ESI) m/z: 264.0 (M+H+). | |

72% | In 1-methyl-pyrrolidin-2-one; at 210 - 220℃; for 4h; | Preparation 84; 2-Cyano-5-fluoropyridine; Add in a 5-L 3-neck roundbottom equipped with overhead stirrer, reflux condenser, thermometer, and N2 line, 5-chloro-2-cyanopyridine (193.0 g, 1. 39 mol) and 1-methyl-2-pyrrolidinone (NMP, 2L). Heat the mixture and stir at 210-220 C for 4 h. Cool the reaction mixture to room temperature, stir overnight, and filter. Wash the filter cake with ethyl ether (1L). Extract the filtrate with water (6L) and ethyl ether (3 X 5L). Combine the organics and back-extract with water (8L) and dry over magnesium sulfate. Concentrate at 25-30 C to give an oily semi-solid, 193 g. Chromatograph over flash silica gel (5% ethyl acetate in hexanes gradually increasing to 10% ethyl acetate in hexanes) to provide the title compound as a white solid. Dissolve the solid in ethyl ether, filter, and add hexanes. Concentrate to low volume to provide a primary crop of pure title compound, 60 g. Repeat the process of crystallization on the filtrate to provide a second crop of highly pure title compound, 24.0 g. (Concentrate the final filtrate to a white solid of product of good quality, and re-chromatograph, conditions as above, to provide an additional 38.6 g of material. ) Obtain a total yield of title compound of 122.4 g, 72% ; 1H NMR (CDCl3) 5 8.59 (d, J= 3.0 Hz, 1H), 7.75 (m, 1H), 7.55 (m, 1H). |

56% | EXAMPLE 1; N-(l-(5-chloropyridin-2-yl)-l-(3-fluoro-5-(trifluoromethyl)phenyl)-2- phenylethyl)-4-(trifluoromethyl)thiazol-2-amine; Procedure 1; [00187] A dry 250 mL round bottomed flask was equipped a stirring bar and fitted to an adapter connected to the vacuum line. The flask was dried under vacuum and then purged several times with nitrogen. Under a stream of nitrogen, l-bromo-3- fluoro-5-(trifluoromethyl)benzene (2.5g, lOJmmoles) was added to the flask and dissolved in anhydrous ether (100 mL). The flask was fitted with a septum which was connected to the nitrogen line via a 16 gauge IV2 PrecisionGlide needle. The stirring solution was cooled to -78C for 10 minutes, n-BuLi (1.6M in hexanes, 6.4 mL. 10.3mmoles) was added drop wise. After 15 minutes, a solution of 5-chloro-2- cyanopyridine (1.42g, 10.3mmoles) in anhydrous THF (10 mL) was added from a syringe. The reaction was stirred for 2 hours at -78C and trimethylchlorosilane (1.41 mL, 10.3 mmoles) was added. The reaction vessel was removed from the acetone/dry ice bath and the reaction was allowed to warm up to room temperature. After 30 minutes, the reaction vessel was cooled to -78C, Benzylmagnesium chloride (2.0M in THF, 5.15 mL, 10.3 mmoles) was added and the reaction was allowed to slowly warm to room temperature for 2h. The reaction was quenched with H2O (10 mL). The crude product was poured into 200 mL ethyl acetate in a 1000 mL separatory <n="168"/>funnel. The light brown solution was washed with saturated aqueous NH4Cl (3 x 100 mL), then with water (2 x 100 mL). The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The crude residue was purified by column chromatography on silica gel ISCO with 95-75% hexanes in ethylacetate to yield 1- (5-chloropyridin-2-yl)-l-(3-fluoro-5-(trifluoromethyl)phenyl)-2-phenylethanamine 994mg (24% yield).
