Reaction Steps

Into a solution of 5.0 g (0.06 mole) of 1,1-dimethypropinylamine in 30 ml acetic ester is dropped, after addition of 50 ml water, at 10° to 15° C., while stirring, a solution of 14.6 g (0.06 mole) chloroformic acid-3-(N-carbethoxyamino)-phenyl ester in 30 ml acetic ester and simultaneously a solution of 8.3 g (0.06 mole) potassium carbonate in 30 ml water, the reaction product crystallizing out. Stirring is continued for 30 minutes while cooling with ice. The product is suction-filtered and washed with ether and water.
