Reaction Steps

The mixture of 7-bromo-6-methoxy-5-methylbenzo[d]thiazol-2-amine (8A) (1.72 g, 6.32 mmol), 4-chlorophenyl boronic acid (1.2 g, 7.67 mmol), K2CO3 (2.63 g, 18.9 mmol), Pd(PPh3)4 (364 mg, 0.315 mmol) in DME (8 ml) and H2O (4 ml) was reacted in microwave at 110° C. for 1 h. Then 4-chlorophenyl boronic acid (100 mg, 0.64 mmol), Pd(PPh3)4 (100 mg, 0.086 mmol) were added and reacted in microwave at 110° C. for 0.5 h and 120° C. for 20 min. The reaction mixture was washed by water, extracted by EtOAc. The organic phase was combined, dried over MgSO4, filtered, concentrated down and purified by silica gel column, eluting by 0-100% EtOAc in hexanes. LCMS-ESI+: calc'd for C15H13ClN2OS: 305.0 (M+H+). Found: 305.1 (M+H+).
