Carbon tetrabromide → HCID 58355381, compound

Participants

Reaction Steps

To a solution (4 ml) of tert-butyl(3S,5R)-3-[{[1-(2-fluorophenyl)-5-(hydroxymethyl)-1H-1,2,3-triazol-4-yl]carbonyl}(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (410 mg) and triphenylphosphine (275 mg) in dichloromethane was added under ice-cooling carbon tetrabromide (350 mg), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (10:90-100:0) was concentrated under reduced pressure to give the object product (442 mg).
