Procedure

A mixture of 6-bromo-pyridine-3-carbaldehyde (1.0 g, 5.38 mmol), 2-methylpropane-2-sulfinamide (715 mg, 5.90 mmol) and titanium (IV) isopropoxide (2.5 mL, 8.53 mmol) in dichloroethane (10 mL) was warmed at 110° C. in the microwave for 15 minutes. The reaction was monitored by TLC (ethyl acetate-hexanes 2:8). The mixture was diluted with dichloromethane (100 mL) and water (5 mL) was added. The mixture was stirred for 10 minutes and then dried over magnesium sulfate. The crude material was purified by silica gel chromatography eluting with a gradient of 0-20% ethyl acetate in hexanes to afford 2-methyl-propane-2-sulfinic acid 1-(6-bromo-pyridin-3-yl)-meth-(E)-ylideneamide
