Reaction Steps

A solution of 33.5 g of 1-(2-nitrophenyl)ethyl bromide and 11.4 g of thiourea in 375 ml absolute ethanol was stirred at reflux temperature for 31/2 hours. The reaction mixture was allowed to cool to room temperature and was concentrated to one-half volume in vacuo. The solution was then cooled to ca. -60° C. and 1-chlorobutane was added until a gummy solid formed. The supernatant was decanted and the residue dried in vacuo to give 38 g of 1-(2-nitrophenyl)ethyl carbamimidothioate hydrobromide as a light orange solid which was not further purified.
