Ethylamine → 1-ethylamino-6-methoxy-3-phenyl-1H-indene-2-carboxylic acid ethyl ester

Participants

Reaction Steps

1-Bromo-6-methoxy-3-phenyl-1H-indene-2-carboxylic acid ethyl ester (100 mg, 0.27 mmol) obtained in Example 18 was dissolved in THF (10 mL), and 2.0 M ethylamine (0.68 mL, 1.35 mmol) in THF was added dropwise thereto. The mixture was stirred for 12 hrs at RT, and the solvent was removed under a reduced pressure. The resulting residue was purified by flash chromatography to obtain 68 mg of the titled compound (yield: 75.6%).
