Reaction Steps

A solution of 2-(ethyl(4-(1,3,3-trimethylspiro[indoline-2,2′-naphtho[1,2-b][1,4]oxazine]-6′-yl)phenyl)amino)ethanol (Example 8, Step 3) (0.085 g, 0.17 mmol) in DCM (5 ml) was treated with triethylamine (0.026 g, 0.26 mmol) in one portion followed by propionyl chloride (0.019 g, 0.21 mmol) and stirred at RT for 18 hrs. The solvent was then evaporated in vacuo and the crude residue purified by column chromatography (silica gel) eluting with 0-10% EtOAc/Petroleum ether, which gave the pure product, 2-(ethyl(4-(1,3,3-trimethylspiro[indoline-2,2′-naphtho[1,2-b][1,4]oxazine]-6′-yl)phenyl)amino)ethyl propionate, as a pale green foam upon evaporation of the solvent in vacuo (0.08 g, 84%).
