Participants

Reaction Steps

3-Chloroperbenzoic acid (0.89 g) was added to a solution of methyl 4-{[(1-methyl-1-phenylethyl)amino]carbonyl}-2-(methylthio)-1,3-thiazole-5-carboxylate (Intermediate 15; 0.63 g) in DCM (25 ml). After stirring overnight the reaction was complete. Aqueous sodium bisulfite was added to quench any unreacted peroxides and the solution was washed with sat. NaHCO3. The organic portion was dried with MgSO4 and concentrated to a yellow solid (0.6 g). NMR: 1.63-1.68 (m, 6H), 3.58 (s, 3H), 3.89 (s, 3H), 7.23 (d, J=7.16 Hz, 1H), 7.34 (t, J=7.63 Hz, 2H), 7.47 (d, J=7.54 Hz, 2H), 8.91 (s, 1H).
