実験手順

Tolvaptan (10.0 g, 22.3 mmol) was dispersed in dichloromethane (100 ml). Pyridine (2.7 ml) was added thereto, and the mixture was stirred. 4-Chlorobutyric acid chloride (3.74 ml) was gradually added to the obtained mixture, and the mixture was stirred at room temperature over night. The reactant was then poured into water, and the mixture was extracted with dichloromethane, washed with a sodium hydrogen sulfate aqueous solution, dried over magnesium sulfate. After filtration and concentration under reduced pressure, the resulted residue was crystallized with diethyl ether. The resulted crystals were collected by filtration, and dried to obtain 10.7 g of 7-chloro-1-[2-methyl-4-(2-methylbenzamido)benzoyl]-2,3,4,5-tetrahydro-1H-benzo[b]azepin-5-yl 4-chlorobutyrate as white powder.
