実験手順

2.5 g of diethylamine dissolved in 30 ml of dichloromethane are added dropwise with stirring to a solution of 10 g of 3-[2-chloroethoxycarbonyl]-5-[1,2,3,4-tetrahydro-1-(3,4-dimethoxybenzoyl)-6-quinolyl]-6-methyl-3,6-dihydro-2H-1,3,4-thiadiazin-2-one and 9 ml of pyridine in 100 ml of dichloromethane and the mixture is subsequently stirred at 20° C. for one hour. The solvent is removed and the mixture is worked up in the conventional manner to give 3-[2-(N,N-diethylamino)ethoxycarbonyl]-5-[1,2,3,4-tetrahydro-1-(3,4-dimethoxybenzoyl)-6-quinolyl]-6-methyl-3,6-dihydro-2H-1,3,4-thiadiazin-2-one; hydrochloride.
