Participants

Reaction Steps

To a solution of (S)-1-amino-2-propanol (9.76 g, 130 mmol)in anhydrous benzene (60 mL) at 0° C. was added benzyl chloroformate (10.23 g, 60 mmol) in anhydrous benzene (120 mL) slowly, in portions, over a period of 20 min while vigorously stirring under an atmosphere of nitrogen. The mixture was stirred for 1 hour at 0° C., then allo/wed to warm to room temperature and stirred for a further 2 hours. The mixture was washed with water (2×) and brine (2×) before the organic layer was dried over anhydrous MgSO4. Evaporation of all solvent gave the title product as an oil. 1H NMR (CDCl3)? 1.22 (d, 3H,) 2.40 (bs, 1H), 3.07 (m, 1H), 3.37 (m, 1H), 3.94 (m, 1H), 5.16 (s, 2H), 5.27 (m, 1H), 7.38 (m, 5H). MS m/z (electrospray) 232 [M+23]30 (100%), 166 (96).
