Hydrochloric Acid → 5-(6-(2-ethyl-6-fluorindoline-1-carbonyl)pyrimidin-4-ylamino)-1,3-dihydrospiro[indene-2,3'-pyrrolo[2,3-b]pyridin]-2'(1'H)-one

Participants

Reaction Steps

63 μL (0.25 mmol) 4M aqueous hydrochloric acid were added to 516 mg (2.00 mmol) (6-chloro-pyrimidin-4-yl)-(2-ethyl-6-fluoro-2,3-dihydro-indol-1-yl)-methanone and 611 mg (2.00 mmol) 5-amino-1,3-dihydrospiro[indene-2,3′-pyrrolo[2,3-b]pyridin]-2′(1′H)-one in 10 mL of 2-pentanol. The reaction mixture was refluxed for 6 h. The reaction mixture was evaporated down using the rotary evaporator and the residue was taken up in DMF. The purification was carried out by preparative HPLC. The product fractions were combined and lyophilised.
