Procedure
16.0 mg (0.100 mmol) benzenesulphonic acid were added to 126 mg (0.500 mmol) 5-amino-1,3-dihydrospiro[inden-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one and 152 mg (0.500 mmol) 6-(6-chloro-pyrimidin-4-carbonyl)-3,4-dimethyl-3H-benzoxazol-2-one in 5.0 mL of 2-pentanol and boiled for 4 h. The reaction mixture was evaporated down and purified by preparative HPLC. The fractions containing the product were combined, the organic solvent was eliminated i.vac. and the aqueous phase remaining was neutralised with 1M aqueous NaOH solution. The product precipitated as a solid was suction filtered, washed with water and dried i. vac.
