Reaction Steps

To a suspension of 2-(4-Iodo-2-oxo-1,2-dihydro-pyridin-3-yl)-4-methyl-6-(1-methyl-piperidin-4-yl)-1H-1,3,6-triaza-s-indacene-5,7-dione Hydrochloride and 2-(4-Chloro-2-oxo-1,2-dihydro-pyridin-3-yl)-4-methyl-6-(1-methyl-piperidin-4-yl)-1H-1,3,6-triaza-s-indacene-5,7-dione Hydrochloride (0.75 g, 1.45 mmol), (R)-3-amino-1-(2,4-dimethylphenoxy)-2-propanol (0.34 g, 1.73 mmol) in EtOH (20 mL) was added Et3N (0.61 mL, 4.35 mmol) and the resulting mixture was heated at reflux for overnight. The reaction mixture was evaporated in vacuo and the residue was purified by flash chromatography (10% (6% NH3/MeOH)/CHCl3) to afford 2-{[4-[(R)-3-(2,4-dimethyl-phenoxy)-2-hydroxy-propylamino]-2-oxo-1,2-dihydro-pyridin-3-yl}-4-methyl-6-(1-methyl-piperidin-4-yl)-1H-1,3,6-triaza-s-indacene-5,7-dione (0.45 g, 57%) as a yellow solid.
