Reaction Steps

In a 25 mL vial, cupric sulfate (1.96 g, 12.3 mmol), 1-methyl-1H-imidazole-2-carbaldehyde (450 mg, 4.09 mmol) and 2-methylpropane-2-sulfinamide (594 mg, 4.9 mmol) were combined with dichloromethane (2 ml) to give a light blue suspension. The reaction mixture was stirred at 25° C. for 15 h then filtered through Celite. The reaction mixture was filtered again through silica gel eluting with ethyl acetate. The crude reaction mixture was concentrated in vacuo to provide 670 mg (76%) of 2-methyl-propane-2-sulfinic acid 1-(1-methyl-1H-imidazol-2-yl)-meth-(E)-ylideneamide as an oil. 1H NMR (300 MHz, CDCl3): δ 8.62 (s, 1H), 7.27 (bs, 1H), 7.08 (bs, 1H), 4.02 (s, 1H), 1.26 (s, 9H).
