- Product Name:1-ETHYL-3-PHENYL-2-THIOUREA
- CAS Number:2741-06-2
- Molecular formula:C9H12N2S
- Molecular Weight:180.27
Yield:2741-06-2 95%
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.
