Procedure

1.4 ml of a 1N aqueous sodium hydroxide solution are added to 0.34 g (0.7 mmol) of methyl 3-(3-{3-methoxy-4-[(propylsulfonyl)amino]benzoyl}imidazo[1,5-a]pyridin-1-yl)benzoate obtained in example 190 in 20 ml of methanol. The reaction medium is heated at 70° C. for 3 hours and then concentrated under reduced pressure. The residue is taken up in water and the aqueous phase obtained is washed with dichloromethane, neutralized by addition of 1.4 ml of 1N hydrochloric acid and then extracted with dichloromethane. The organic phase obtained is dried over sodium sulfate and concentrated under reduced pressure. 0.19 g of a yellow solid is collected, which solid is salified in the sodium salt.2.1H2O form. Melting point: 145° C.; 1H NMR (d6-DMSO): 0.96-1.01 (3H, t), 1.71-1.83 (2H, m), 3.16-3.19 (2H, m), 4.00 (3H, s), 7.33-7.70 (2H, m), 7.36-7.38 (1H, m), 7.52-7.97 (2H, m), 8.04-8.07 (2H, m), 8.27-9.85 (2H, m), 8.44 (1H, s), 8.64 (1H, s), 9.25 (1H, m)
