Hydrogen was introduced into a mixture of 1.85 g of 3-(N-methyl-N-phenylamino)-2-hydroxypropylazide (prepared as described in Preparation 89), 0.9 g of 10% w/w palladium-on-carbon and 30 ml of ethanol for 1.5 hours. At the end of this time, the atmosphere was replaced with nitrogen, the palladium-on-carbon catalyst was removed from the reaction mixture by filtration, and the filtrate was concentrated by evaporation under reduced pressure, to give 1.6 g of the title compound which decomposed at 136° C.
