Hydrochloric Acid → N-[4-(chloromethyl)phenyl]-7-phenyl-3,4-dihydronaphthalene-2-carboxamide

Participants

Reaction Steps

To a mixture of N-[4-(hydroxymethyl)phenyl]-7-phenyl-3,4-dihydronaphthalene-2-carboxamide (566 mg), lithium chloride (135 mg), triethylamine (446 μl) and dichloromethane (50 ml) was added methanesulfonyl chloride (172 μl), and the mixture was stirred at room temperature for 2 hours. To the reaction mixture was added dilute hydrochloric acid. The organic layer was separated, washed with saturated sodium chloride solution, dried with anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give N-[4-(chloromethyl)phenyl]-7-phenyl-3,4-dihydronaphthalene-2-carboxamide (494 mg) as colorless crystals.
