Procedure
0.022 g (0.61 mmol) of 4-(2-chloroethyl)morpholine hydrochloride and 0.189 g (1.37 mmol) of potassium carbonate are added, under an inert atmosphere, to 0.3 g (0.55 mmol) of 3-(3-{[3-(4-fluorobenzyl)-1-methyl-2,4-dioxo-1,2,3,4-tetrahydroquinazolin-6-yl]carbonyl}imidazo[1,5-a]pyridin-1-yl)benzoic acid in 8 ml of DMF. After stirring for 18 h at ambient temperature and then for 8 hours at 50° C., the reaction medium is hydrolysed with water, and extracted with ethyl acetate. The organic phase is washed with water, dried over sodium sulphate, filtered, and then concentrated under reduced pressure. The yellow solid obtained is purified by silica gel column chromatography, elution being carried out with a dichloromethane/methanol (95/5) mixture. 0.61 ml of a 1N aqueous solution of hydrochloric acid is added to 0.334 g of the yellow solid obtained, in 5 ml of methanol. The reaction medium is stirred for 1 hour at ambient temperature. Dyethyl ether is added and then the reaction medium is filtered. The precipitate obtained is rinsed with dyethyl ether and then dried under reduced pressure at 50° C. overnight. 0.298 g of a yellow solid is obtained.
