Propyl chloroformate → HCID 11653183, compound

Participants

Reaction Steps

6-Amino-1-(4-methoxyphenyl)-1H-indole-3-carbonitrile (30 mg, 0.12 mmol), is suspended in EtOH (300 μL). Propyl chloroformate (168 μL, 1.5 mmol) is added, and this mixture is stirred at room temperature overnight. The addition of triethylamine (300 μL), followed by another hour of stirring at room temperature, completes the reaction. This reaction mixture is loaded directly onto a silica column, and is eluted with CH2Cl2. Another silica column (3/2, ether/hexanes) is needed to fully purify the product, [3-cyano-1-(4-methoxy-phenyl)-1H-indol-6-yl]-carbamic acid propyl ester (19 mg, 45%), as a white solid.
