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 1-(3-propyl)-piperazine (60.5 mg, 0.387 mmol) in 1,4-dioxane (1 mL). The reaction mixture was stirred at room temperature for 20 min, then 40° C. for 1 h. Upon completion of the reaction, the reaction mixture was filtered through Celite (ethyl acetate eluent), concentrated, and used without further purification. LCMS-ESI+ calc'd for C34H43ClN5O3S (M+H+): 636.3; Found: 636.2 (M+H+).
