Participants

Reaction Steps

Thiourea (180 mg, 2.4 mmol) was added to a solution of 1-methyl benzyl bromide (0.3 ml, 2.2 mmol) in ethanol (10 ml) at room temperature. The mixture was heated under reflux for 5 hours. 3-Methanesulfonyl-5,5-dimethyl-4,5-dihydroisoxazole (420 mg, 2.4 mmol) and potassium carbonate (330 mg, 2.4 mmol) were added and the mixture was heated under reflux for 3 hours. The mixture was allowed to cool to room temperature, poured into water and the mixture extracted with ethyl acetate. The combined organic phases were washed with water, dried over magnesium sulfate and concentrated. The crude product was purified by chromatography on silica gel (eluent: ethyl acetate/hexane) to give the product as a white solid (210 mg, 43% yield) which was used without further purification.
