Procedure

The compound prepared in Example 82 (202 mg), tert-butyl 4-(aminomethyl)piperidine-1-carboxylate (0.266 g) and triethylamine (0.607 mL) were combined in ethanol (1.5 mL) and heated at 80° C. for 17 hours. The reaction mixture cooled to room temperature, diluted with a saturated aqueous sodium bicarbonate solution and extracted with ethyl acetate. The combined organics were dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate:hexane=1:1 to 2:1) to obtain the title compound (316 mg) having the following physical data.
