In N,N-dimethyl-formamide; | Reference example 4 N-tert-Butoxycarbonyl-3-(2-methoxyethoxy)azetidine To a suspension of 0.25 g of 60% sodium hydride in 5 ml of dried N,N-dimethylformamide, a solution of 1.00 g of N-tert-butoxycarbonyl-3-azetidinol in 3 ml of dried N,N-dimethylformamide was added under stirring at room temperature. The mixture was stirred at room temperature for 30 minutes, then added dropwise with a solution of 0.98 g of <strong>[16427-44-4]2-methoxyethyl methanesulfonate</strong> in 2 ml of dried N,N-dimethylformamide, and stirred at the same temperature for 4 hours. The reaction solution was poured into ice water, and extracted with ethyl acetate. The extract was washed successively with water and saturated brine, and dried over sodium sulfate, and then the solvent was evaporated under reduced pressure. Theresidue was purified by column chromatography (silica gel, ethyl acetate: n-heptane = 1: 3) to obtain 0.67 g of a colorless liquid.

46% | Add sodium hydride (2.77 g, 60% w/w, 69.2 mmol) to a solution of 3-hydroxy- azetidine-1-carboxylic acid tert-butyl ester (10.9 g, 62.9 mmol) in dimethyl sulfoxide (100 mL). Stir the mixture for 30 min and then add 3-bromo-6-fluoroanisole (15.5 g, 75.5 mmol). Heat the mixture to 65 0C overnight. Cool the mixture to room temperature and then dilute the solution with saturated ammonium chloride and brine and extract with ethyl acetate. Wash the organics five times with brine, then dry over sodium sulfate and filter. Concentrate and purify via silica gel chromatography using a 0-45% gradient of ethyl acetate/hexane to give 10.4 g (46%) of the title compound as a clear oil. |

318 mg | Preparation Example 352 To a mixture of tert-butyl 3-hydroxyazetidine-1-carboxylate (420 mg) and N,N-dimethylformamide (12.5 mL) was added potassium tert-butoxide (260 mg) under ice-cooling, followed by stirring for 1 hour, and then <strong>[313340-08-8]3,5-dichloro-6-ethylpyrazine-2-carboxamide</strong> (500 mg) was added thereto, followed by stirring for 1 hour. The reaction mixture was poured into ice water, followed by extraction with ethyl acetate. The organic phase was washed with saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent; hexane:ethyl acetate), and then washed with a mixed solvent of hexane:diisopropyl ether to obtain tert-butyl 3-[(5-carbamoyl-6-chloro-3-ethylpyrazin-2-yl)oxy]azetidine-1-carboxylate (318 mg) as a white solid. |
