Methyl triflate → 10-Methyl-9-(phenoxycarbonyl)acridin-10-ium trifluoromethanesulfonate

Participants

Reaction Steps

Phenyl acridine-9-carboxylate (530 mg, 1.7 mmol) was dissolved in methylenechloride (5 mL) under argon and methyl trifluoromethanesulfonate (1 mL, 8.8mmol) was added. The solution was stirred overnight at room temperature to yield a thick yellow precipitate. This precipitate was filtered, washed with ether and dried to obtain the product as yellow crystals. 1H NMR (acetone-d6) δ5.22 (s, 3H), 7.47-7.71 (m, 5H), 8.23-9.07 (m, 8H).
