Participants

Reaction Steps

A solution of 2.4 g (4.3 mmol) of N-(1-benzyloxycarbonylcyclohexyl)-N-pentanoyl-N-[2'-(1H-tetrazol-5-yl)biphenyl-4-ylmethyl]-amine in 40 ml of dioxan is hydrogenated with the addition of 0.5 g of Pd/C (10%) and worked up, in a manner analogous to that described in Example 73. The N-(1-carboxycyclohexyl)-N-pentanoyl-N-[2'-(1H-tetrazol-5-yl)biphenyl-4-ylmethyl]-amine is thus obtained in the form of colourless crystals (from ethyl acetate) melting between 134° and 136°.
