Procedure

The product from Example 68A (40 mg, 0.16 mmol) was mixed with tert-butyl hexahydro-1H-pyrrolo[3,4-c]pyridine-5(6H)-carboxylate (55 mg, 0.24 mmol) and to this was added 2-methoxyethanol (0.65 mL), and N,N-diisopropylethylamine (0.20 mL, 1.2 mmol); the reaction was heated at 115° C. for 16 hours, cooled, diluted with CH2Cl2 (25 mL) and washed with 1 M NaOH (10 mL). The aqueous layer was extracted with CH2Cl2 (15 mL). The combined organics were dried (MgSO4), filtered, concentrated and chromatographed and eluted with a gradient of 1:0 to 0:1 CH2Cl2:EtOAc to provide the title compound.
