Participants

Reaction Steps

1.6 ml (21 mmol, 20 eq.) of trifluoroacetic acid is added to a solution of tert-butyl 4-((3,3-diphenylpropyl){[3-(trifluoromethyl)anilino]carbonyl}amino)-1-piperidine carboxylate (600 mg, 1.04 mmol) in dichloromethane. The reaction medium is agitated for 90 minutes then concentrated. Dichloromethane is added and the organic phase is washed with a saturated solution of sodium bicarbonate, dried over magnesium sulphate, filtered and concentrated under vacuum in order to isolate 490 mg (yield=98%) of a white foam.
