Procedure

68 g (0.313 mol) of ethyl N-allyl-N-(2,2-dimethoxyethyl)-carbamate are heated at 100° C. for an hour with 150 ml of formic acid. The mixture is poured onto ice, extracted several times with methylene chloride, and the organic phases are washed with sodium hydrogen carbonate solution, dried over magnesium sulphate, concentrated and distilled.
