Pyridine hydrochloride (1.0 g, 8.65 mmol) and 2-cyano-6-methoxybenzothiazole, 2, (0.5 g, 2.63 mmol) were added to a 5 mL microwave flask with a stirbar. Nitrogen gas was added to the reaction vessel immediately before it was shut. The flask was heated to 200° C. using a power level of 150 W for 40 minutes in a Biotage microwave synthesizer. The reaction was stirred at 600 rpm. The reaction was cooled and neutralized with sodium bicarbonate. During neutralization, the crude product precipitated from the solution as a yellow solid. The precipitate was filtered, and the filtrate was washed three times with ethyl acetate. Combination of the crude product from the ethyl acetate washes and the yellow precipitate and purification on a silica column (70:30 hexanes:ethyl acetate, dry loaded) yielded 408.7 mg (88percent) of the pure product. 1H NMR (300 MHz, CD3OD): delta 7.13 (1H, dd, J=9 Hz), 7.36 (1H, d, J=2.1 Hz), 7.95 (1H, d, J=9 Hz). LRESI-MS: calculated for [C8H4N2OS] 176.0. found 176.1.
