Reaction Steps

To a solution of (S)-tert-butyl 3-(5-(4-(6-(1-tert-butoxy-2-ethoxy-2-oxoethyl)-7-(4-chlorophenyl)-5-methylbenzo[d]thiazol-2-yl)pyridin-2-yl)-1H-indazol-1-yl)azetidine-1-carboxylate (54 mg, 0.070 mmol) in isopropanol (3 mL) was added HCl in Dioxane (3 mL, 4 N in dioxane). The reaction mixture was stirred at room temperature. After the reaction finished, the reaction mixture was diluted by EtOAc, washed by saturated NaHCO3, back-extracted by EtOAc, the organic phase was dried over MgSO4, filtered, concentrated down, purified by silica gel column, eluting by 0-100% EtOAc in hexanes to give the product. LCMS-ESI+: calc'd for C37H36ClN5O3S: 666.2 (M+H+); found: 666.3.
