Procedure

The above compounds were prepared according to the procedure reported in the literature: see S. Muthusamy Synth. Commun. 2002, 32, 3247. To a stirred solution of ethyl 4-oxo-2-(2-(trifluoromethyl)phenylamino)-4,5-dihydrothiazole-5-carboxylate (1.1 g, 3.3 mol), tert-butyl acrylate (Aldrich, 2.5 mL, 16.5 mmol) in EtOH (10 mL) was added DBU (Aldrich, 0.25 mL, 1.6 mmol). The mixture was stirred at r.t. overnight and concentrated in vacuo. The crude product was purified by silica gel chromatography. MS: 461 (M+1).
