Procedure

The product of Example 268D (0.115 g, 0.30 mmol) was reacted with 1,3-thiazole-5-carbaldehyde (0.35 g, 3.0 mmol) in N,N-dimethylacetamide (3 mL) in a sealed tube at 140° C. for 80 minutes in a microwave reactor. The reaction was cooled to 25° C. and concentrated under vacuum. The resulting residue was triturated with 0.1 M HCl (20 mL) and filtered to give the title compound.
