Reaction Steps

Step-4: A degassed mixture of 2-bromo-6-butylbenzo[d]thiazole (142 mg, 0.5 mmol), (4-(methoxycarbonyl)phenyl)boronic acid (135 mg, 0.75 mmol), Pd2(dba)3 (9 mg, 0.01 mmol), Xphos (9.5 mg, 0.02 mmol), potassium phosphate (207 mg, 1.5 mmol) in dioxane (2 mL) under nitrogen atmosphere was stirred at 100° C. for 6 h. The reaction mixture was cooled to RT, evaporated and extracted with dichloromethane, washed with brine, dried over anhydrous sodium sulfate and evaporated. The crude product was purified by preparative TLC to afford methyl 4-(6-butyrylbenzo[d]thiazol-2-yl)benzoate, MS (ESI+) m/z 340.2 [M+1]+
