Versuchsvorschrift

Prepare a solution of 1-amino-2-propanol (5.0 g, 66.6 mmol) in methylene chloride (250 mL) at 0° C. under nitrogen. Add Hünig's Base (11.6 mL, 66.6 mmol) followed by benzoyl chloride (7.7 mL, 66.6 mmol). Warm the reaction mixture to room temperature and stir overnight. Wash the solution sequentially with brine (100 mL) and 1M HCl (75 mL), dry (Na2SO4), filter, and concentrate to afford 10.0 g of N-(2-hydroxypropyl)benzamide. MS: m/e=180 (MH+)
