실험 절차

The reaction solution containing compound (19) was then added to a 0.2M diazomethane solution (20 ml) in diethylether and the mixture so obtained was allowed to react at room temperature for 1 hour. The resulting reaction solution was filtered and the filtrate was concentrated to give the titled compound (20) (55 mg) as a syrup.
