Procedure

Methanol (4.0 mL) was added to 3-(3-amino-2-fluorobenzyl)-4-methyl-7-(thiazol-2-yloxy)-2-oxo-2H-1-benzopyran (compound 1h-3-4) (200 mg), and benzaldehyde (0.053 mL) was added to the resultant suspension while stirring at room temperature. The suspension was heated under reflux for 3 hours. The reaction solution was then cooled to room temperature, and the solvent was distilled away under reduced pressure. The resultant residue was purified by silica gel chromatography (amino gel) (dichloromethane) to yield the title compound (233 mg).
