Water → 2-Acetamidomethyl-1-(3-tert-butyldiphenylsilyloxymethyl-2,4-dichlorophenyl)pyrrole

Participants

Reaction Steps

To a mixture of 2-aminomethyl-1-(3-tert-butyldiphenylsilyloxymethyl-2,4-dichlorophenyl)pyrrole (87 mg) and pyridine (20.3 mg) in dichloromethane (1 ml) was added acetic anhydride (20.9 mg) under ice-cooling, and the mixture was stirred for 3 hours at ambient temperature. The mixture was poured into water and extracted with dichloromethane. The organic layer was washed with 1H hydrochloric acid, water, saturated sodium bicarbonate solution and brine, dried over magnesium sulfate and evaporated in vacuo to give 2-acetamidomethyl-1-(3-tert-butyldiphenylsilyloxymethyl-2,4-dichlorophenyl)pyrrole (94 mg) as amorphous powder.
