Reaction Steps

The product of Example 304F (0.800 g, 1.73 mmol) and cyclopropane carboxaldehyde (1.60 mL, 20.76 mmol) in N,N-dimethylacetamide (2 mL) were reacted at 120° C. for 60 minutes in a microwave reactor in a sealed tube. The reaction was concentrated under a stream of nitrogen warmed through a manifold heated to 165° C. The resulting residue was triturated with diethyl ether and filtered to give the title compound (0.750 g, 84%).
