Procedure
N,N-diisopropylethylamine (1.4 mL, 7.9 mmol) and triphosgene (1.2 g, 3.9 mmol) in 20 mL of dry methylene chloride were added to a solution of 2-fluoro-4-{2-[(2-hydroxy-1,1-dimethylethyl)amino]-1,3-thiazol-4-yl}benzonitrile (955 mg, 3.3 mmol), prepared in the previous step, in 50 mL of dry methylene chloride at 0° C. The reaction was stirred at 0° C. for 3 h and then allowed to warm to room temperature. The reaction was washed with 1×100 mL of 2N HCl. The aqueous layer was extracted with methylene chloride (2×100 mL). The combined organic layers were dried over anhydrous MgSO4, filtered and concentrated under reduced pressure to give 1.0 g of a yellow solid. Purification of the solid on silica gel using a stepwise gradient of 5% to 40% ethyl acetate-hexane gave the title compound (450 mg, 43%) as a yellow solid, mp 204-206° C.
