Versuchsvorschrift

1.58 g of platinum oxide were added to a solution of 21.0 g of 1-(4-methoxyphenyl)-1-methylethyl azide [prepared as described in step (a) above] in 100 ml of methanol. The reaction mixture was then stirred for 5 hours under a stream of hydrogen. At the end of this time, the mixture was filtered, diluted with methylene chloride, and washed with an aqueous solution of sodium hydrogencarbonate, with water and with a saturated aqueous solution of sodium chloride, in that order. It was then dried over anhydrous magnesium sulfate, and concentrated by evaporation under reduced pressure, to give 17.2 g (yield 95%) of the title compound.
