実験手順

A mixture of 2.25 g (5 mmoles) of 1-(1-methoxycarbonyl-2-methylprop-2-enyl)-3-phenylacetamido-4-succinimidothio-azetidin-2-one (prepared as described in Example 2) and 1.4 ml (10 mmoles) of triethylamine in 100 ml of tetrahydrofuran was stirred at 65°C for 25 minutes. The reaction mixture was evaporated, treated with 25 ml of ethyl acetate and evaporated once more. The residual foam was dissolved in 50 ml of ethyl acetate, treated with charcoal and concentrated to a small volume. The desired product crystallized upon cooling. There was obtained 1-(1-methoxycarbonyl-2-methylpropenyl)-3-phenylacetamido-4-succinimidothio-azetidin-2-one.
