Reaction Steps

To the solution of ((S)-2-tert-butoxy-2-(7-(4-chlorophenyl)-5-methyl-2-(3-(1-methyl-1H-indazol-5-yl)-2-oxotetrahydropyrimidin-1(2H)-yl)benzo[d]thiazol-6-yl)ethyl pivalate (20 mg) in THF/MeOH (1 mL/1 mL) was added sodium hydroxide solution (1 mL, 1 N, 1 mmol). The mixture was heated at 50° C. for 12 hours. The mixture was diluted with water, and extracted with ethyl acetate. The organic phase was washed with water and brine, dried over sodium sulfate and filtered. Concentration gave (S)-1-(6-(1-tert-butoxy-2-hydroxyethyl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-2-yl)-3-(1-methyl-1H-indazol-5-yl)tetrahydropyrimidin-2(1H)-one. LCMS-ESI+: calc'd for C32H34ClN5O3S: 604.2 (M+H+); Found: 604.3 (M+H+).
