Participants

Reaction Steps

N-({1-[4-(3-Methoxy-pyridin-4-yl)-cyclohexyl]-azetidin-3-ylcarbamoyl}-methyl)-3-trifluoromethyl-benzamide (0.101 g, 0.206 mmol, as prepared in Example 8) was dissolved in anhydrous dichloromethane (10 mL) under Ar, treated with 0.83 N boron tribromide in dichloromethane (Aldrich, 2.00 mL, 1.66 mmol), and stirred at ambient temperature for 24 h. After quenching with saturated aqueous NaHCO3, the reaction was stirred at ambient temperature for 30 mins and extracted thrice with 3:1 EtOAc/2-propanol. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo giving a gold gum that was purified by preparative thin layer chromatography on silica gel (15% MeOH in CH2Cl2, 0.6N in ammonia), giving the title compound as a pale yellow solid.
