Reaction Steps

To methyl 4-chlorosulfonylbenzoate (4 g, 17.05 mmol), N-methylthiazol-2-amine (1.95 g, 17.05 mmol), 1,2-dichloroethane (20 mL), and triethylamine (2.38 mL, 17.05 mmol) were added and the reaction was heated at 100° C. in a pressure vessel for 20.5 hours on a heat block. The solvent was evaporated under reduced pressure. The crude compound was dissolved in dichloromethane and filtered. The filtrate was purified by silica gel chromatography utilizing a gradient of 0-30% ethyl acetate in dichloromethane to yield methyl 4-[methyl(thiazol-2-yl)sulfamoyl]benzoate (4.22 g, 79.2%). 1H NMR (400 MHz, DMSO) δ 8.16 (d, J=8.5 Hz, 2H), 7.95 (d, J=8.5 Hz, 2H), 7.46 (d, J=3.6 Hz, 1H), 7.44 (d, J=3.6 Hz, 1H), 3.89 (s, 3H), 3.39 (s, 3H). ESI-MS m/z calc. 312.0, found 313.3 (M+1)+; Retention time: 1.52 minutes (3 min run).
