Procedure

The product of Example 268D (0.054 g, 0.15 mmol) was reacted with cyclopentanone (0.95 g, 11.3 mmol) in N,N-dimethylacetamide (1 mL) in a sealed tube at 135° C. for 60 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.
