Procedure

The product of Example 48 (300 mg, 0.67 mmol), trans-4-aminocyclohexanol hydrochloride (226 mg, 1.5 mmol), and triethylamine (0.42 mL, 3 mmol) were combined in THF (15 mL) and stirred under Ar at 50° for 2 days. The solvents were removed in vacuo, and the residue was partitioned between EtOAc and H2O. The organic phase was washed with H2O, satd aq NaCl, dried over anhyd Na2SO4, filtered and evaporated to give the crude product. Flash chromatography with 0-20% EtOAc/CH2Cl2 followed by recrystallization from CH2Cl2/hexane gave the product as a white-crystalline solid. mp 158-160°, LC MS m/z=481 (MH+) Retention time=2.08 min.
