Participants

Reaction Conditions

Reaction Steps

200 g of molecular sieve are initially introduced into 1,000 ml of ethanol and 105 g (1 mol) of aminoacetaldehyde dimethyl acetal and70 g (1 mol) of crotonaldehyde are added. The mixture is allowed to stand at room temperature overnight, decanted off from molecular sieve and cooled to 0° C., and 40 g of sodium borohydride are added in 1 g portions. The mixture is then stirred overnight at room temperature and concentrated, the residue is taken up in 500 ml of water and potassium carbonate is added until an organic phase separates. This is extracted using chloroform, dried over potassium carbonate and concentrated, and the residue is distilled.
