Procedure
The 4-cyanobenzenemethanamine obtainable by modified Gabriel synthesis, when reacted with chloroethylisocyanate, yields 1-[(4-cyanophenyl)methyl]-3-(2-chloroethyl)urea which when treated with potassium tert.butoxide in dimethylformamide is easily cyclised into the 1-[(4-cyanophenyl)methyl]-2-imidazo-lidinone; catalytic hydrogenation then leads to the desired 4-[(2-oxo-1-imidazolidinyl)methyl]benzenemethanamine.
