실험 절차

When an equivalent amount of 4-pyrimidone is substituted for 1-ethoxycarbonyl-2H-indazolin-3-one and 2-bromochloroethane is substituted for 1,2-dibromoethane in the procedure of Example 19, 2-(1,6-dihydro-6-oxopyrimidin-1-yl)ethyl chloride is isolated after column chromatography (4-pyrimidone, Aldrich, 34%, B).
