実験手順
2.13 ml (28.68 mmol) of trifluoroacetic acid are added to 610 mg (1.43 mmol) of tert-butyl 3-[3-(methoxycarbonyl)-4-nitrobenzoyl]imidazo[1,5-a]pyridine-6-carboxylate in 2 ml of dichloromethane and the mixture is stirred at ambient temperature for 5 hours. The reaction medium is concentrated under reduced pressure and then the residue obtained is taken up in acetone. The precipitate formed is filtered off, washed with acetone and dried. 450 mg of a yellow powder are obtained. Melting point: 290° C.; 1H NMR (d6-DMSO): 3.90 (3H, s), 7.78 (1H, d), 8.04 (1H, s), 8.12 (1H, d), 8.26 (1H, d), 8.68 (1H, d), 8.75 (1H, s), 10.26 (1H, s)
