Procedure

To a mixture of 4-phenoxycyclohexanone (0.091 g, 0.475 mmol) and N-[2-oxo-2-({2-oxo-2-[(3R)-pyrrolidin-3-ylamino]ethyl}amino)ethyl]-3-(trifluoromethyl)benzamide in 2% AcOH/CH2Cl2 (10 mL) was added NaB(OAc)3H (0.134 g, 0.634 mmol). After being stirred overnight at room temperature under N2, the reaction mixture was diluted with EtOAc and washed with saturated Na2CO3. The aqueous was extracted with EtOAc (3×). The combined organic layers were dried (MgSO4), concentrated and flash chromatographed (EtOAc to EtOAc:MeOH:Et3N=9:1:0.1) to give 0.12 g of the title compound. MS (EI) calcd: (M+H)+=490.2; found 490.0.
