Reaction Steps

To (S)-methyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-chloropyrimidin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (40.0 mg, 0.077 mmol) was added (S)-1-isopropyl-3-methylpiperazine (33.1 mg, 0.232 mmol) in 1,4-dioxane (1 mL) and triethylamine (15.7 mg, 22 μL, 0.155 mmol). The reaction mixture was stirred at 60° C. for 4 d, after which the reaction mixture was filtered through Celite (ethyl acetate eluent), concentrated, and used without further purification. LCMS-ESI+ calc'd for C33H41ClN5O3S (M+H+): 622.3; Found: 622.2 (M+H+).
