반응 단계
2.00 g (4.54 mmol) of the 2-(4-carboxypiperidino)-4-(3,4-methylenedioxybenzylamino)-6-chloroquinazoline prepared in Example 222 was dissolved in a mixture comprising 25 ml of tetrahydrofuran and 25 ml of ethanol under heating, followed by the dropwise addition of 0.31 ml (4.78 mmol) of methanesulfonic acid. The obtained mixture was cooled by allowing to stand to precipitate crystals. The crystals were recovered by filtration, washed with tetrahydrofuran, and air-dried to give 2.21 g of the title compound.
