Reaction Steps

To 2-Bromomethyl-5,8-dimethyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (3.36 g, 10.9 mmol) and sodium azide (5.1 g, 78.5 mmol), dimethylformamide (73.2 ml) were added, and stirred for 1 hour in a bath at 100° C. After cooling, the mixture was condensed, and the resultant residue was dissolved in chloroform, which was washed with water and dried. After condensation, the precipitated crystals were subjected to recrystallization (chloroform-ether) to obtain 2.76 g of the title compound as colorless crystals (93.8%).
