Procedure

A saturated solution of ammonia in ethanol (40 ml) was added over 40 minutes to a mixture of 2-[bis(2-methoxyethyl)amino]phenyl isothiocyanate (7.5 g) and ethanol (10 ml) which had been cooled to 10° C. The mixture was stirred at 0° C. for 8 hours and then stirred without cooling for 16 hours. The solvent was then removed by evaporation and the residue purified by chromatography on a silica column eluted with a 1:4 mixture of ethyl acetate and hexane and then a 1:1 mixture of ethyl acetate and hexane to give 1-((2-[bis(2-methoxyethyl)amino]phenyl)) thiourea (m.p. 118°-119° C.).
