Potassium Carbonate → HCID 59739561, compound

Participants

Reaction Steps

4-Bromomethyl-5-cyano-3-methyl-isothiazole (50% purity) (0.65 g, 1.5 mmol) was dissolved in ethanol (30 ml) and thiourea (242 mg, 3.2 mmol) was added. The mixture was stirred at room temperature until the solids were dissolved. 3-Methane-sulfonyl-5,5-dimethyl-4,5-dihydroisoxazole (540 mg, 3.2 mmol) and potassium carbonate (440 mg, 3.2 mmol) were added and the mixture was heated under reflux for 1 hour. The solids were removed by filtration and the filtrate was concentrated. The crude product was purified by chromatography on silica gel (eluent: ethyl acetate/hexane) to give the product (0.25 g, 62% yield). 1H-NMR (400 MHz, CDCl3): 1.44 (6H, s, Me), 2.6 (3H, s, Me), 2.8 (2H, s, CH2), 4.4 (2H, s, CH2).
