الإجراء التجريبي

Thiourea (50 g, 657 mmol) and 1-bromohexane (119 mL, 723 mmol) were heated at reflux under nitrogen in ethanol (500 mL) for 20 h. Ethanol was evaporated, and the thick oil stirred in diethyl ether (500 mL). The product precipitated spontaneously. After filtration one obtained 144.5 g (91%) of white crystals, m.p. 75° C.
