실험 절차

To a solution of o-tolylamine (21.4 g, 0.20 mol) and Et3N (22.3 g, 0.22 mol) in CH2Cl2 was added 2,2-dimethyl-propionyl chloride (25.3 g, 0.21 mol) at 10° C. The mixture was stirred overnight at room temperature, washed with aq. HCl (5%, 80 mL), saturated NaHCO3 solution and brine, dried over Na2SO4 and concentrated under vacuum to give 2,2-dimethyl-N-o-tolyl-propionamide (35.0 g, 92%).
