Reaction Steps

0.21 g of 3-methyl-5-(2-chlorophenyl)-8-(3-butynyloxycarbonyl)-6,7,8,9-tetrahydro-1H,3H-pyrido[4',3':4,5]thieno[3,2-f][1,4]diazepin-2-one was dissolved in 10 ml of dimethoxyethane, to which 0.11 g of sodium hydrogencarbonate and 0.22 g of phosphorus pentasulfide were added, followed by heating at 80° C. for 3 hours. After completion of the reaction, dichloromethane and methanol were added, and the mixture was filtered, followed by addition of silica gel to the resultant filtrate and evaporating the solvent to dryness. Silica gel column chromatography (elution solvent: dichloromethane:methanol=99:1) was used for purification, thereby obtaining 0.15 g of the intended compound.
