Reaktionsschritte

The title compound (2.16 g, 45%) was prepared from 1-(t-butyldimethylsilyloxy)-2-propanone (3.77 g, 0.02 mol), dimethylamine hydrochloride (1.71 g, 0.02 mol) and potassium cyanide (1.37 g, 0.02 mol) in water (50 ml) in a similar manner to that described in D1. An additional purification step was passage of the compound through SCX resin, elution with DCM to remove the starting material and then elution with 1 M ammonia in methanol to elute the title compound. 1H NMR (CDCl3) δ: 0.00 (6H, d), 0.81 (9H, s), 1.38 (3H, s), 2.25 (6H, s), 3.36 (1H, d), 3.78 (1H, d).
