---|---|---|
95.9% | With acetic acid; at 100℃; for 2.0h; | Example 1A; 2- (Acetylamino) butanoic acid; 163 g (1. 58 mol) 2-Aminobutanoic acid are dissolved in acetic acid, and 242 g (2.37 mol) acetic anhydride are added dropwise. The mixture is stirred for 2 h at 100C until completion of reaction, then the solution is evaporated to dryness in vacuo. The solid residue is suspended in ethyl acetate, filtered and washed with diethyl ether. Yield: 220 g (95.9%) IH-NMR (Methanol-d4): o/ppm 0.97 (t, 3 H), 1.65-1. 93 (m, 2 H), 1.99 (s, 3 H), 4.29 (q, 1 H) ppm. |
