Reaction Steps

5-amino-2-methylbenzothiazole (52.2 mg, 0.31 mmol) was mixed with 1-phenylisatin (69.7 mg, 0.31 mmol) and heated at 140° C. for 3 h. The resulting crude product was purified by preparative TLC using ethyl acetate/hexane (6:4) as the eluent to give the desired product as a yellow solid (36.9 mg, 32.3%). 1H NMR Data: δ 7.9-6.7 (m, 12H), 2.9 (s, 3H). ESI-MS m/z found 370 (MH+).
