Reaction Steps
Sodium azide (490 mg) and pyridinium chloride (870 mg) were added to a solution of 8-(3-methoxy-4-pentyloxycinnamoyl)amino-1,4-benzodioxane (560 mg; synthesized in reference example 2) in dry dimethylformamide (3 ml). In an atmosphere of argon, the solution was stirred for 1.5 hrs at 100° C. The reaction solution cooled to room temperature was poured into 1N hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was washed with water and a saturated aqueous solution of sodium chloride, dried, and then concentrated under reduced pressure. The residue was recrystallized from ethyl acetate to give the title compound (390 mg) having the following physical data:
