Reaction Conditions:

in dichloromethane at 20; for 6 h;

Steps:

Preparation of Thioureas 3a-z

General procedure: Method A; To a solution of isothiocyanate 1 (1.0 mmol) in dichloromethane(10 mL) was added the corresponding amine 2(1.2 mmol), and the mixture was stirred at room temperatureuntil isothiocyanate was consumed (TLC). After that, the organicphase was washed with 5% aqueous hydrochloric acid (3×10 mL), dried with anhydrous sodium sulfate and evaporatedin a rotary evaporator to afford the pure thiourea 3, whichdid not require any further purification.
