Ammonium nitrate → HCID 22127973, compound

Participants

Reaction Steps

A solution of 240 mg of Cer(IV) ammonium nitrate in 1 ml of water was added dropwise at room temperature to a solution of 118 mg of (3RS,4RS)-3-(1,4-dimethoxy-naphthalen-2-ylmethoxy)-4-[4-(2-phenethyloxy-ethoxy)-phenyl]-piperidine in 10 ml of acetonitrile. The reaction solution was stirred at room temperature for 15 minutes and subsequently evaporated under reduced pressure. The residue was partitioned between methylene chloride and water, the organic phase was dried and evaporated under reduced pressure. For purification, the crude product was chromatographed on silica gel using a 9:1 mixture of methylene chloride and methanol as the eluent. There were obtained 95 mg (85% of theory) of (3RS,4RS)-2-[4-[4-(2-phenethyloxy-ethoxy)-phenyl]-piperidin-3-yloxymethyl]-[1,4]naphthoquinone as a red solid; MS: 512 (M+H)+.
