Reaction Steps
20 g of molecular sieve are added to 12 g (0.1 mol) of 1,1-dimethoxyacetone in 100 ml of ethanol, and 7 g (0.12 mol) of allylamine are then added dropwise. The mixture is allowed to stand overnight at room temperature, the liquid phase is decanted off from the molecular sieve and cooled to 0° C. in an ice-bath, and 4 g (0.1 mol) of sodium borohydride are added in small portions. The mixture is stirred overnight at room temperature, concentrated and taken up in 100 ml of water, and this mixture is saturated with potassium carbonate and extracted five times using 100 ml portions of chloroform. The extracts are dried over potassium carbonate, concentrated and distilled.
