Procedure
A solution of 27.3 mg of HBTU in 0.2 ml of dimethylformamide is added, at a temperature in the region of 20° C., to a solution of 20 mg of 2-(1H-indazol-3-yl)-1H-benzimidazole-5-carboxylic acid in 0.42 ml of anhydrous dimethylformamide. After stirring at a temperature in the region of 20° C. for one hour, 15.7 ml of benzylamine are added, followed by addition of 12.4 ml of N,N-diisopropylethylamine dissolved in 0.32 ml of dimethylformamide. After 20 hours, at a temperature in the region of 20° C., the reaction medium is concentrated under reduced pressure, at a temperature in the region of 40° C. The crude residue obtained is dissolved in DMSO and purified by preparative LC-MS. The fractions containing the desired product are combined and concentrated under reduced pressure at a temperature in the region of 40° C. 20 mg of 21H-indazol-3-yl)-1H-benzimidazole-5-carboxylic acid benzylamide are thus obtained in the form of a cream-coloured powder, the characteristics of which are as follows:
