4-Benzylphenol → cis-1-(4-Benzylphenoxy)-2-tert-butoxycarbonylaminoindane

Participants

Reaction Steps

The title compound was prepared in a similar manner to Preparation 18 from (±)N-tert-butoxycarbonyl-1,2-iminoindane (2 g, 8.7 mmol), 4-benzylphenol (1.59 g, 8.7 mmol), pyridinium p-toluenesulfonate (30 mg) and chloroform (50 ml). After a reaction time of 3 h, the reaction was diluted with chloroform (50 ml) then washed sequentially with saturated aq. sodium bicarbonate, water and brine. After drying over Na2 SO4, volatiles were removed in vacuo and the residue subjected to column chromatography on neutral alumina eluting with 10% diethyl ether in hexanes to afford the title compound (1.4 g) as a foam
