反応手順
In a round bottom flask maintained under argon atmosphere, ethyl 8-amino-1,4,4-trimethyl-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxylic acid methylamide (13.00 g, 45.400 mmol) was dissolved into anhydrous dimethoxyethane (800 mL); cesium iodide (11.795 g, 45.400 mmol), bisublimated iodine (5.761 g, 22.698 mmol), copper(I) iodide (2.594 g, 13.621 mmol), and iso-amyl nitrite (9.107 mL, 68.100 mmol) were added in that order and the mixture was heated to 70° C. for 22 hours.
