실험 절차

A mixture of solution of 4-[4-(2,6-Dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-phenoxymethyl]-1-(3-trifluoromethyl-benzyl)-pyrrolidine-2-carboxylic acid methyl ester (25 mg, 0.039 mmol) in THF (3 ml) and MeOH (1 ml) was added aq. solution of LiOH (3 mg, 0.079 mmol) in H2O (1 ml) at 0° C. and it was stirred for 2 hrs. Reaction mixture was concentrated, residue was diluted with water and acidified with aq. HCl. The aqueous layer was extracted with ethyl acetate and washed with brine. The ethyl acetate layer was concentrated and purified by column chromatography to offer 4-[4-(2,6-Dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-phenoxymethyl]-1-(3-trifluoromethyl-benzyl)-pyrrolidine-2-carboxylic acid as viscous oil (18 mg, 75%).
