Procedure

Following the method used to prepare 24a, the use of 1a (0.19 mmol) and oxalyl chloride in THF followed by allowing the intermediate acid chloride to react with MeOH (3 mL) provided 52 mg (81%) of product 9 as a white solid, mp 192-193° C. 1H NMR (300 MHz, DMSO-d6) δ 2.57 (s, 3H), 3.84 (s, 3H), 6.88 (d, J=7 Hz, 1H), 6.95-6.98 (m, 2H), 7.24 (t, J=8 Hz, 1H), 7.26-7.29 (m, 2H), 7.41 (d, J=9 Hz, 1H), 12.52 (s, 1H). LC-MS (CI): m/z 332.1 [(M+H)+ C17H14ClNO2S requires 331.04]. Purity (100%). Calcd for C17H14ClNO2S: C, 61.53; H, 4.25; N, 4.22; S, 9.66; Cl, 10.68. Found: C, 61.25; H, 4.24; N, 4.14; S, 9.56; Cl, 10.64.
