実験手順
Tripiperidinomethane (1.06 g) is added to a solution of 7-dimethoxyphosphorylamino-3-methyl-2-(4-nitrobenzyloxycarbonyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene (0.9 g) in ethyl acetate (40 cc) at 45° C., and the reaction mixture is stirred for 18 hours at 45° C. and diluted with ethyl acetate (20 cc). The organic solution is washed with distilled water (3×20 cc) and then with a saturated solution of sodium chloride (2×15 cc), dried over magnesium sulphate and concentrated to dryness under reduced pressure (30 mm Hg; 4 kPa) at 30° C. The residue obtained is recrystallised from ethyl acetate (5 cc), and 7-dimethoxyphosphorylamino-2-(4-nitrobenzyloxycarbonyl)-8-oxo-3-(2-piperidinovinyl)-5-thia-1-azabicyclo[4.2.0]oct-2-ene (E isomer) (0.2 g) is obtained in the form of an orange-yellow crystalline powder, m.p.=220°-221° C.
