Participants

Reaction Steps

To a solution of 6-azido-3,4-dihydroisoquinolin-1(2H)-one (0.24 g) obtained in Example 132b) and ethyl 3-keto-n-hexanoate (0.25 ml) in ethanol (7 ml) was added 28% sodium ethoxide in ethanol solution (0.60 ml) at room temperature, and the mixture was stirred for 3 hr. The solvent was evaporated under reduced pressure, and water was added to the obtained residue. The mixture was washed with ethyl acetate, 1N hydrochloric acid was added to acidify the aqueous solution, and the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound as a yellow solid (0.22 g, 57%).
