Procedure

Under a nitrogen atmosphere, 2-[2-(allyloxycarbonylamino)thiazol-4-yl]-2-(Z)-methoxyiminoacetic acid (248 mg, 0.87 mmol) was suspended in methylene chloride (5 ml) and the suspension was cooled to 0° C. 2-Chloro-4,6-dimethoxy-1,3,5-triazine (153 mg, 0.87 mmol) then N-methylmorpholine (0.095 ml, 0.87 mmol) were added and the resultant solution was stirred at 0° C. for 30 minutes. A methylene chloride solution (10 ml) of allyl 3-(propionyl)-7-(R,S)-amino-8-oxo-1,5-diazabicyclo[3.3.0]octa-2-ene-2-carboxylate hydrochloride (0.87 mmol) was added followed by the addition of N-methylmorpholine (0.095 ml, 0.87 mmol). The solution was allowed to warm gradually to room temperature over 1.5 hours and then the methylene chloride was removed in vacuo. The resultant residue was flash chromatographed on silica gel eluted with 10% hexane:ethyl acetate to give 270 mg, 57% yield of allyl 3-(propionyl)-7-(R,S)-[2-(2-(allyloxycarbonylamino)thiazol-4 -yl)-2-(Z)-methoxyiminoacetamido]-8-oxo-1,5-diazabicyclo[3.3.0]octa-2-ene-2-carboxylate: n.m.r. (90 MHz, CDCl3): δ 1.11 (t, 3, J=7.2), 2.39-2.79 (m, 2), 3.09 (dd, 1, J=9 and 11.7), 3.95 (s, 3), 3.80-4.24 (m, 3), 4.42 (1/2ABq, 1, J=12.5), 4.60-4.96 (m, 4), 5.16-5.68 (m, 4), 5.72-6.22 (m, 2), 7.09 (s, 1), 8.28 (br.d, 1, J=7.2), 9.55 (br.s, 1); i.r. (CHCl3): 3230, 1733, 1679, 1554, 1423, 1377, 1353, 1044 cm-1 ; u.v. (EtOH): λhd max=208 (ε=21522), 228 (ε=22084), 261 (ε=13612), 365 (ε=8122); f.d.m.s. (m/e): M+ +1=547; m.p. 183°-186° C.
