Reaction Steps
A mixture of (E)-4-dimethylamino-1,1-dimethoxy-but-3-en-2-one (49.6 g, 286 mmol) and formamidine acetate (44.7 g, 429 mmol) was heated at 120° C. for 4 h. After cooling to room temperature the mixture was poured into water and extracted with dichloromethane. The combined organic extracts were then dried over sodium sulfate, filtered and evaporated. Purification by distillation afforded the title product (31 g, 70%) as a colourless liquid. Bp 59-60° C. at 1.3 mbar. MS: m/e=155.0 [M+H]+.
