Acetyl chloride → 1-acetylamino-3-phenyl-6-(3-phenyl-propoxy)-1H-indene-2-carboxylic acid ethyl ester

Participants

Reaction Steps

1-Amino-3-phenyl-6-(3-phenyl-propoxy)-1H-indene-2-carboxylic acid ethyl ester (30 mg, 0.07 mmol) prepared in Example 21 was dissolved in dichloromethane (10 mL), and acetyl chloride (30.15 mg, 0.37 mmol) and triethylamine (40 mg, 0.37 mmol) were added thereto in order at 0° C. The mixture was stirred for 24 hrs at RT, washed with saturated saline and extracted with dichloromethane. The organic layer was separated, dried over anhydrous MgSO4 and concentrated under a reduced pressure. The resulting residue was purified by flash chromatography to obtain 15 mg of the titled compound (yield: 45%).
