Participants

Reaction Steps

A mixture of 2-(4-fluoro-phenyl)-oxirane (1.38 g, 10.0 mmol), thiourea (760 mg, 10.0 mmol) and silica gel (200 mg) in CH2Cl2 (10 mL) was stirred at room temperature for 12 hours. Water (20 mL) was added to the suspension and the mixture was extracted with CH2Cl2 (2×20 mL). The combined organic layers were dried over MgSO4, filtered and concentrated to provide the title product.
