35% | H181 (0.667mmol) was dissolved in DMF (lOmL) and cooled to 0°C with ice bath. To this solution under nitrogen were added in sequence sodium hydride (106mg, 2.67mmol, 4.0eq) and 2-chloro-5-(chloromethyl)thiazole (0.298mL,2.67mmol, 4.0eq). The reaction mixture was stirred for 4 hours then treated with 1M HC1 (10ml). After extraction with ethyl acetate, the organic layer was washed with water and brine, and dried over anhydrous Na2S04. The residue after rotary evaporation was purified by column chromatography over silica gel to give the title compound (66mg, 35percent yield). 1H NMR (400 MHz, DMSO-d6): delta 9.16 (s, 1H), 7.92 (d, J = 4 Hz, 1H), 7.34 (d, J = 8.8 Hz, 2H), 7.13 (dd, J = 8.0 2.7 Hz, 1H), 5.35 (s, 2H) and 4.92 (s, 2H) ppm.
