Ammonia gas was passed into a stirred solution of n-propyl acetoacetate (prepared by the method of Fisher, J.A.C.S., 1934, 56, 1766; 72 g.) in diethyl ether (100 ml.) at ambient temperature for 20 hours. The solution was then dried over sodium sulphate, filtered and distilled under reduced pressure to give n-propyl 3-iminobutyrate (18.2 g.), b.p. 114°-118° C./20 mm Hg.
