The product of Example 304F (0.285 g, 0.62 mmol) in N,N-dimethylacetamide (1.5 mL) was reacted with cyclobutanone (0.85 mL, 10.9 mmol) in a sealed tube in a microwave reactor at 130° C. for 45 minutes. The reaction was cooled to 25° C., concentrated under a stream of nitrogen warmed through a manifold heated to 165° C. and the resulting residue was triturated with diethyl ether to give the title compound (0.178 g, 56%).
