Reaction Steps

To a solution of ethyl 4-(4-chlorobenzyl)-2-(pyridin-4-yl)thiazole-5-carboxylate (12.8 g, 35.7 mmol) in THF (200 mL) and water (100 mL) was added 1.0 M LiOH (46.4 mL, 46.4 mmol) and the resulting solution was stirred at room temperature overnight. The mixture was acidified to pH 4 with 1 N HCl. The precipitated solids were filtered, washed with water and dried to give 11 g of the title compound as an a white solid. (93% yield). LC/MS (FA) ES+ 331. 1H NMR (400 MHz, d6-DMSO) δ: 13.86 (br s, 1H), 8.72-8.71 (m, 2H), 7.89-7.87 (m, 2H), 7.36-7.29 (m, 4H), 4.50 (s, 2H).
