Reaction Steps

Into a 100-mL round-bottom flask, was placed a solution of ethyl 3-(4-ethylphenyl)-5-methanesulfonyl-1,2-thiazole-4-carboxylate (150 mg, 0.44 mmol, 1.00 equiv), methanol (15 mL), MeONa (119.47 mg, 5.00 equiv). The resulting solution was stirred for 2 h at 70° C. in an oil bath. The resulting solution was extracted with 2×15 mL of dichloromethane and the organic layers combined. The resulting mixture was washed with 2×30 mL of brine, dried over anhydrous Na2SO4. The solids were filtered out. The resulting mixture was concentrated under vacuum. This resulted in 141.4 mg (crude) of methyl 3-(4-ethylphenyl)-5-methoxy-1,2-thiazole-4-carboxylate as white oil. Mass spectrum (ESI, m/z): Calcd. for C15H17NO3S, 292.1 (M+H). found 292.1.
