Reaction Steps

7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl trifluoromethanesulfonate (5F) from above reaction was dissolved in DMF (3 ml). Tributylvinyltin (130 uL), PdCl2(PPh3)2 (27 mg, 0.039 mmol) and LiCl (49 mg, 1.17 mmol) were added. The reaction mixture was stirred at 120° C. in microwave for 30 min. The reaction mixture was diluted by ethyl acetate, washed with saturated NaHCO3 solution and extracted with ethyl acetate. The organic layer was dried over MgSO4, filtered, concentrated and purified by silica gel column (0-50% ethyl acetate/hexanes). LCMS-ESI+: calc'd for C16H20ClNS: 286.0 (M+H+). Found: 286.1 (M+H+).
