3-(4-Phenylphenoxy)-2-hydroxypropylazide → 1-Amino-3-(biphenyl-4-yloxy)propan-2-ol

Participants

Reaction Steps

Hydrogen was introduced into a mixture of 2.94 g of 3-(4-phenylphenoxy)-2-hydroxypropylazide (prepared as described in Preparation 83), 0.3 g of 10% w/w palladium-on-carbon and 60 ml of ethanol for 3 hours. At the end of this time, insolubles were removed by filtration, and the filtrate was concentrated by evaporation under reduced pressure, to give 2.84 g of the title compound, melting at 137.7° to 146.8° C.
