Procedure

Dibenzyl phosphorochloridate was added to the solution of benzyl 3-(2-(benzyloxy)-4-(ethoxymethoxy)-5-isopropylphenyl)-4-(1-methyl-1H-indol-5-yl)-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1-carboxylate and potassium carbonate in acetone. The reaction mixture was stirred at room temperature overnight. After removal of solvent, the reaction mixture was purified by column chromatography to produce pale yellow oil, which was hydrogenated to give the desired.
