実験手順
A solution of oxalyl chloride (0.040 mole) in dichloromethane (20 mL) is added dropwise to an ice bath cooled solution of 4-(3-(5-(aminosulfonyl)-4-chloro-2-[(2-furanylmethyl)amino]benzoyloxy)propoxy)(4-oxo)butanoic acid (810) (0.040 mole) in dichloromethane (50 mL). The reaction is stirred at ambient temperature for 5 hours. The reaction solution is washed with 5% aqueous sodium bicarbonate, with water, and then with a saturated sodium chloride solution. The organic layer is dried over sodium sulfate, filtered and concentrated in vacuo to provide 4-(3-(5-(aminosulfonyl)-4-chloro-2-[(2-furanylmethyl)amino]benzoyloxy)propoxy)(4-oxo)butanoyl chloride (813). See eg., D. L. Musso, et. al., J. Med. Chem., (2003) 46: 409.
