PROCEDURE
实验过程
Prepared by the same procedure as described for the preparation of (4-{[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-ylcarbamoyl]-methyl}-phenyl)-carbamic acid tert-butyl ester (example 1, step 5) except that (4-{[6-amino-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-ylcarbamoyl]-methyl}-phenyl)-methyl-carbamic acid tert-butyl ester was used in place of (4-{[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-ylcarbamoyl]-methyl}-phenyl)-carbamic acid tert-butyl ester. Purified by chromatography using silica eluted with 3% v/v methanol in chloroform to give (4-{[6-amino-1-cyclopropylmethyl-3-(2-fluoro-benzyl)-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-ylcarbamoyl]-methyl}-phenyl)-methyl-carbamic acid tert-butyl ester as a colorless solid foam (63% yield from [4-(tert-butoxycarbonyl-methyl-amino)-phenyl]-acetic acid).
