P-Cresol → HCID 178426866, compound

Participants

Reaction Steps

A mixture of trans-2-{[4-(4-benzyloxy-phenyl)-cyclohexyl]-methyl-amino}-ethanol (0.3 g, 0.88 mmol), p-cresol (96 mg, 0.88 mmol), triphenylphosphine (232 mg, 0.88 mmol), diethyl-azodicarboxylate (154 mg, 0.88 mmol) and THF was stirred at rt for 3h. The solvent was evaporated and the rsidue was treated with MeOH/H2O (3:1, 50 ml) and hexane (50 ml). The aq. layer was extracted with hexane (30 ml). The combined hexane extracts were dried and evaporated. The residue was purified by chromatography (SiO2, CH2Cl2—MeOH 95:5) to give trans-[4-(4-benzyloxy-phenyl)-cyclohexyl]-methyl-(2-p-tolyloxy-ethyl)-amine (135 mg, 69%, white solid, MS: m/e=430.5 (M+H+)).
