Procedure

Propargyl bromide (14.7 g of 80% solution in toluene, 0.1 mol) was added to a stirred solution of aminoacetaldehyde diethyl acetal (13.3 g, 0.1 mol) in THF (200 mL). After 2 h the THF was removed and the residual oil was partitioned between ether and sodium hydroxide solution. Evaporation of the ether gave an oil which was chromatographed on silica gel to give 4.7 g of 2,2-diethoxy-N,N-bis-(2-propynyl)ethylamine and 8.1 g of 2,2-diethoxy-N-(2-propynyl)ethylamine.
