4-Methylmorpholine → [4-(1,1-Dioxo-1lambda6-isothiazolidin-2-yl)-3-methoxyphenyl][4-(4-methylbenzoyl)piperidin-1-yl]methanone

Participants

Reaction Steps

A mixture of 4-(1,1-dioxo-1λ6-isothiazolidin-2-yl)-3-methoxybenzoic acid (285 mg) described in Preparation Example 21, (piperidin-4-yl) (p-tolyl)methanone hydrochloride (252 mg) and N-methylmorpholine (0.12 mL) was dissolved in a solution of methanol (3 mL) and water (2 mL), 4-(4,6-dimethoxy[1.3.5]triazin-2-yl)-4-methylmorpholinium chloride hydrate (349 mg) was added, and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (chloroform:methanol) to give the title compound (344 mg).
