실험 절차

To a solution of [1-[[[[3-[[[4-oxo-7,8-bis(phenylmethoxy)-4H-pyrido[1,2-a]pyrimidin-3-yl]carbonyl]amino]-2-oxo-1-imidazolidinyl]sulfonyl]amino]carbonyl]-2-oxo-3-azetidinyl]carbamic acid, phenylmethyl ester (1.35 g, 1.66 mmol) in 65 ml of N,N-dimethylformamide, N-methyl-N-trimethylsilyl trifluoroacetamide (1.66 g, 8.33 mmol) was added. After 20 minutes 0.45 g of palladium on carbon was added, and the mixture was hydrogenolyzed for 1 hour. The catalyst was removed by filtration, and to the filtrate (Z)-2-amino-α-[[2-(diphenylmethoxy)-1,1-dimethyl-2-oxoethoxy]imino]-4-thiazoleacetic acid, 1-benzotriazole ester (0.83 g, 1.5 mmol) was added. After stirring overnight, the solvent was distilled off, and the residue triturated with 20 ml of water. The resulting solid was filtered off with suction and dried in vacuo. Yield of crude product: 1.28 g.
