Procedure

To a 0° solution of methyl amino{4-[2-(1-pyrrolidinyl)ethoxy]phenyl}acetate dihydrochloride (1.67 g; 4.55 mmol) in dichloromethane (10 mL) was added 4-but-2-ynyloxy-benzenesufonyl chloride followed by triethyl amine was dropped in. The mixture was stirred at room temperature overnight and then diluted with dichloromethane. The organic layer was washed with water and brine, dried over sodium sulfate, filtered and concentrated. The residue was purified using column chromatography on silica gel eluting with ethyl acetate to obtain 2.52 g of methyl ({[4-(2-butynyloxy)phenyl]sulfonyl}amino){4-[2-(1-pyrrolidinyl)ethoxy]phenyl}acetate as an oil. Yield 92.6%. Electrospray Mass Spec 487.1 (M+H)+.
