Participants

Reaction Steps

11 g (0.039 mole) of Compound d obtained in Reference Example 4 was dissolved in 100 ml of tetrahydrofuran, and 30 ml (0.39 mole) of 40% methylamine was added with ice cooling, followed by stirring at room temperature for one hour. Then, the solvent was evaporated under reduced pressure, and water was added to the residues. The precipitate was collected by filtration and dried, to afford 9.2 g of Compound w (yield: 87%).
