Acetyl chloride → HCID 58742487, compound

Participants

Reaction Steps

DIPEA (80 μL, 0.5 mmol) and acetyl chloride (30 μL, 0.5 mmol) were added to a solution of 1,1-dimethylethyl [((1R,2R)-2-{[(5-chloro-1H-indol-2-yl)carbonyl]amino}-2,3-dihydro-1H-inden-1-yl)amino]acetate (Method 8, 200 mg, 0.5 mmol) in THF (10 mL). The reaction was stirred at ambient temperature for approximately 1 h. The volatiles were removed by evaporation under reduced pressure the residue dissolved in EtOAc (50 mL), washed with water (2×10 mL), brine (10 mL) and dried (MgSO4). The volatiles were removed by evaporation under reduced pressure and the residue purified by column chromatography (EtOAc:isohexane 1:1) to afford the title compound (168 mg, 76%) as a white solid.
