37% | With sodium iodide; In N,N-dimethyl-formamide;Heating / reflux; | A solution of 1-chloro-2-methyl-2-propanol (2.23 g, 97percent, 0.02 mol), potassium phthalimide (3.780 g, 98percent, 0.02 mol) and sodium iodide (60 mg, 4 mmol) in anhydrous DMF (40 mL) was heated to reflux overnight. The solvent was evaporated under reduced pressure. The resulting product was triturated with a mixture of 3:2 ethyl acetate/hexanes and the ensuing white precipitate was removed by filtration. The yellow filtrate was concentrated under reduced pressure and purified by flash chromatography in a mixture of 2:3 ethyl acetate/hexanes. The impure product thus isolated was triturated with hot hexanes (125 mL) and filtered to remove an insoluble white impurity. After evaporation of the solvent under reduced pressure, the obtained white solid was recrystallized in hexanes. The product was yielded as colorless crystals that were collected by filtration and dried under high vacuum (1.63 g, 37percent yield). m.p.: 104-105° C.; TLC Rf 0.20 (2:3 ethyl acetate/hexanes); FTIR (KBr): 3524, 3456, 3097, 3031, 2973, 2930, 1773, 1698, 1611, 1466, 1427, 1389, 1319, 1190, 1076, 990, 965, 912, 890, 838, 766, 724, 712, 638 cm-1; 1H-NMR(500 MHz, CDCl3): delta 1.26 (s, 6H, 2 CH3), 2.74 (s, 1H, OH), 3.75 (s, 2H, CH2), 7.72 (dd, 2H, Jo=5.44 Hz, Jm=3.04 Hz, 2 Hc),, 7.85 (dd, 2H, Jo=5.42 Hz, Jm=3.06 Hz, 2 Hb); 13C-NMR(126 MHz, CDCl3): delta 27.6 (2 CH3), 49.3 (CH2), 71.6 (CMe2), 123.6 (2 Cb), 132.0 (2 Ca), 134.3 (2 Cc), 169.3 (2 CO). |
