Reaction Conditions

Reaction Steps

To a solution of ethyl hydrogen (α,α-dimethylbenzyl)malonate (4 g, 0.016 mole) in toluene was added triethylamine (2.23 ml, 0.016 mole) and diphenylphosphoryl azide (4.4 g, 0.016 mole). The reaction mixture was heated at 100° C. for 2.5 h, cooled to 5° C., and treated with 1.4 ml (0.016 mole) of morpholine. After stirring overnight at room temperature, the toluene solution was washed successively with 1N HCl and aqueous sodium bicarbonate solution. The dried organic solution was evaporated to a residue which was purified by column chromatography on silica gel. There was obtained 3.7 g (69%) of product after trituration with hexane, m.p. 93°-94° C.
