The reaction mixture was then concentrated and the residue was subjected to column chromatography on silica gel. Elution was carried out with a mixture of chloroform and methanol (10:1 V/V). The fractions containing the desired compound were collected and concentrated under reduced pressure. The residue was precipitated with n-hexane to give 4-[4-(3-indolyl)piperidinomethyl]-2-(3-methylureido)thiazole (540 mg).
