The same procedure as in Example 1 was repeated except that in a deprotective reaction, two catalysts, i.e., 23.4 mg of tris(dibenzylideneacetone)dipalladium and 59.1 mg of tetrakis(triphenylphosphine)palladium were used, 0.14 ml of aniline was used as a trapping agent, and 110.3 mg of allyl (1S,5R,6S)-6-[(1R)-1-allyloxycarbonyloxyethyl]-2-hydroxymethyl-1-methyl-1-carbapen-2-em-3-carboxylate and 196 mg of 2-[N-allyloxycarbonyl-N-(aminosulfonyl)amino]methyl-3-methylimidazo[5,1-b]thiazole were used, thereby obtaining 14.2 mg of the title compound.
