실험 절차
A solution of 3.9 g of 5-(5-ethoxycarbonylpentyl)-imidazo[1,5-a]pyridine in 40 ml of n-butanol is saturated with methylamine and heated on a steam bath for 56 hours in a pressure bottle. The reaction mixture is evaporated to dryness; the resulting product is first crystallized from ether and then recrystallized from 1:1 ethyl acetate-ether to yield the 5-[5-(N-methylcarbamoyl)pentyl]-imidazo[1,5-a]pyridine melting at 118°-22°.
