Participants

Reaction Steps

To a methanol solution of 32 mg of N-(3-chloro-phenyl)-hydroxy-7-amino-N-(tetrahydro-pyran-2-yloxy)-benzofuran-2-carboxamidine was 200 mg of acidic Dowex resin. The resulted solution was stirred at reflux temperature for 1 h. The reaction mixture was filtered and concentrated under vacuum. The crude product was purified using a chromatotron and eluting with 5-10% methanol/dichloromethane to give 18 mg of 7-amino-N-(3-chloro-phenyl)-N′-hydroxy-benzofuran-2-carboxamidine in 62% yield.
