Participants

Reaction Steps

A solution of 1-chloro-5-chlorosulphonylisoquinoline (613 mg, 2.34 mmol) in methylene chloride saturated with ammonia gas (20 mL) was stirred at RT for 18 h, concentrated in vacuo to a white solid and purified by column chromatography upon silica gel (preabsorbed) using EtOAc-hexanes (1:1) as eluant to give 1-chloro-5-sulphamoylisoquinoline as a white solid (206 mg, 0.85 mmol).
