Reaction Steps

57 mg (0.23 mmol) 5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one, 80 mg (0.23 mmol) 6-(6-chloro-pyrimidin-4-ylamino)-4-methyl-3H-benzoxazol-2-one and 69 mg (0.50 mmol) potassium carbonate were combined in 1.5 mL NMP and stirred for 2 h at 130° C. Then the reaction mixture was cooled, acidified with 1M aqueous hydrochloric acid solution and stirred for 1 h at 50° C. The reaction mixture was diluted with water, the precipitate was taken up in DMF and purified by preparative HPLC. The product-containing fractions were combined and freeze-dried.
