Benzoyl chloride → benzamide, N-(2-hydroxy-1,1-dimethylethyl)-

Participants

Reaction Steps

To a 250 ml dichloromethane solution containing 89 g (1.0 mol) 2-amino-2-methyl-1-propanol at 0° was added dropwise with stirring 70 g (0.5 mol) benzoyl chloride in 250 ml dichloromethane. The reaction mixture was warmed to room temperature and stirred for several hours. The 2-amino-2-methyl-1-propanol hydrochloride was removed from the reaction mixture by filtration and was thoroughly washed with dichloromethane. The filtrate and washings were combined and the dichloromethane removed under reduced pressure to afford 67.55 g (0.35 mol), 70%, 2-benzoylamino-2-methyl-1-propanol as a white solid, mp 80°-82°, sublimation at 75° (0.2 mm); ir (KBr) 1630 (c=o) cm-1 ; pmr (CDCl3) δ 1.50 (s, 6H), 3.67 (s, 2H), 5.27 (bs, 1H), 6.92 (bs, 1H) and 7.1 - 8.3 (m, 5H) ppm.
