3-Chloropropanesulphonyl chloride → [4-(5-Cyclopropyl-3-methylpyridin-2-yl)piperazin-1-yl][6-(1,1-dioxo-1lambda6-isothiazolidin-2-yl)-4-methylpyridin-3-yl]methanone dihydrochloride

Participants

Reaction Steps

Using [4-(5-cyclopropyl-3-methylpyridin-2-yl)piperazin-1-yl](6-fluoro-4-methylpyridin-3-yl)methanone (1.25 g) described in Preparation Example 140, 4-methoxybenzylamine (2 mL) and 3-chloropropane-1-sulfonyl chloride (0.55 ml) and by the reaction and treatment in the same manner as in Example 223, the title compound (950 mg) was obtained via (6-amino-4-methylpyridin-3-yl) [4-(5-cyclopropyl-3-methylpyridin-2-yl)piperazin-1-yl]methanone and [4-(5-cyclopropyl-3-methylpyridin-2-yl)piperazin-1-yl][6-(1,1-dioxo-1λ6-isothiazolidin-2-yl)-4-methylpyridin-3-yl]methanone.
