실험 절차

A microwave vial was charged with (S)-ethyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (75 mg, 0.15 mmol), 1-methyl-1H-benzo[d]imidazol-6-ylboronic acid (34 mg, 0.19 mmol), then Pd(PPh3)4 (34 mg, 0.03 mmol). The vial was flushed with argon, diluted with dioxane (1.5 mL) and to this was added 2M aqueous K2CO3 (0.25 mL, 0.50 mmol). The vial was sealed, heated to 100° C. for 2 hours, and then allowed to cool to room temperature. The mixture was diluted with EtOAc, dried over Na2SO4, filtered, and concentrated in vacuo. The crude residue was purified by silica gel column chromatography (0-10% MeOH/CH2Cl2 gradient) to afford the desired product. LCMS-ESI+: calc'd for C30H31ClN3O3S: 548.2 (M+H+); Found: 548.3 (M+H+).
