Reaction Steps

A 5 mL microwave reaction tube was charged with 2-(4-isopropylpiperazin-1-yl)-4-(tributylstannyl)thiazole (33 mg, 0.066 mmol), (S)-methyl 2-(2-bromo-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-6-yl)-2-tert-butoxyacetate (40 mg, 1.2 eq.), Pd(PPh3)4 (15 mg, 15 mol %), CuI (5 mg, 30 mol %) and dioxane (1 mL). The reaction was heated to 110° C. in oil bath for 1 hour. Reaction mixture was diluted with ethyl acetate and saturated NaF aqueous solution was added and stirred for 30 minutes. Extracted with ethyl acetate and the organic layer was concentrated and purified via Combiflash (0-100% ethyl acetate in hexane) to give desired compound. LCMS-ESI+: calc'd for C31H38ClN4O3S2: 613.2 (M+H+); Found: 613.4 (M+H+).
