실험 절차

A solution of 0.6 g (3.5 mmol) of [(4-chloro-phenyl)oxy]ethylamine (Chim. Ther. 1973, 8, 259-270) and 1.3 g (5.8 mmol) of ethyl [(phenyloxy-carbonyl)oxy]acetate, prepared in Step 1.1., in 30 ml of toluene is heated at 60° C. overnight. It is evaporated to dryness and the product is purified by chromatography on silica gel, eluting with a 30/70 mixture of ethyl acetate and cyclohexane. This gives 0.7 g of oily product, containing ˜10% of cyclized oxazolidine dione product, used as it is in the following step.
