Procedure: The product of Example 268D (0.073 g, 0.2 mmol) was reacted with (3R)-3-methylcyclohexanone (1.12 g, 10.0 mmol) in N,N-dimethylacetamide (2 mL) in a sealed tube at 135° C. for 45 minutes in a microwave reactor. The reaction was cooled to 25° C. and concentrated under vacuum. The resulting residue was triturated with diethyl ether (3 mL) and filtered to give the title compound. concentrated under vacuum The resulting residue was triturated with diethyl ether (3 mL) filtered
