Reaction Steps

Water was added to a mixture (307 mg) of 1-(4-[3-[5-((R)-1-aminoethyl)-4-ethyl-4H-[1,2,4]triazol-3-yloxy]-phenyl]-piperazin-1-yl)-ethanone obtained in Example 27-(2) and triethylamine hydrochloride, 3,4-dichlorobenzenesulfonyl chloride (0.13 ml), and K2CO3 (355 mg). The mixture was stirred at room temperature for 15 hours. The precipitated solid was filtered and purified by column chromatography (NH SiO2, MeOH/CHCl3=1/50) to give the titled compound (Compound 697) (117 mg, colorless syrup).
