2,2-Diethoxyethylamine → HCID 13911324, compound

Participants

Reaction Steps

One gram of platinum oxide catalyst was added to 100 ml of ethanol, through which hydrogen was passed with stirring for 30 minutes. Then, 54.06 g (0.3 mol) of 2-methoxy-3,4-methylenedioxybenzaldehyde (1) and 40.78 g (0.3 mol) of aminoacetaldehyde diethylacetal (98 % purity) in 100 ml of ethanol were added to carry out hydrogenation with stirring at room temperature for 8.5 hours. The catalyst was filtered out and the solvent was distilled off under vacuum to obtain 89.43 g of N-(2-methoxy-3,4-methylenedioxybenzyl)aminoacetaldehyde diethylacetal (2) (yield 100 %) as an oil. IR and NMR spectra of the resultant product are listed below. ##STR20##
