To 4-[4-(5-{2-[(methylsulphonyl)oxy]phenyl}-4,5-dihydro-1,2-oxazol-3-yl)-1,3-thiazol-2-yl]piperidinium chloride (500 mg) in dichloromethane (6 ml) under argon were added 2-chloro-2-oxoethyl acetate (154 mg) and triethylamine (342 mg). The reaction mixture was stirred at room temperature for 18 hours. Then water was added thereto, and it was filtered, dried and concentrated. Purification by column chromatography gave 2-{4-[4-(5-{2-[(methylsulphonyl)oxy]phenyl}-4,5-dihydro-1,2-oxazol-3-yl)-1,3-thiazol-2-yl]piperidin-1-yl}-2-oxoethyl acetate (170 mg, 30%).
