실험 절차
9.2 g of β-chloroethyl isothiocyanate dissolved in 20 ml tetrahydrofuran are added dropwise to a solution of 9 g of dicyclopropylmethylamine in 70 ml tetrahydrofuran. The reaction mixture is kept at a temperature of from 0° to +5° C. during the addition, then maintained at room temperature for 2 hours. The solvent is evaporated to dryness and the residue, consisting essentially of N-(1,1-dicyclopropylmethyl) N'-(β-chloroethyl) thiourea, is recovered and used without any further purification for the next step of the synthesis.
