Reaction Steps

The compound obtained in Example 23 is dissolved in dioxane (2 ml), and thereto is added a 4M solution of hydrogen chloride in dioxane (5 ml), and the mixture is stirred at room temperature. To the reaction mixture is further added a 4M solution of hydrogen chloride in dioxane (5 ml), and the mixture is stirred for three hours. The reaction mixture is concentrated under reduced pressure, and the residue is purified by silica gel column chromatography (solvent; chloroform:methanol=30:1) to give 3-methoxycarbonyl-2-[4-(hydrazinocarbonyl)phenyl]-4-(3,4,5-trimethoxyphenyl)-1(2H)-isoquinolinone hydrochloride as listed in Table 4.
