4-Trifluoromethyl-2-(4-trifluoromethyl-phenyl)-pyrimidine-5-carboxylic acid → 2-(4-{[4-Cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylcarbamoyl]-methyl}-phenoxy)-2-methyl-propionic acid tert-butyl ester

Participants

Reaction Steps

In analogy to the procedures described in example 26B] and 124C], 4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylamine (prepared from 4-trifluoromethyl-2-(4-trifluoromethyl-phenyl)-pyrimidine-5-carboxylic acid, see example 133], in analogy to the procedures described in examples 125B] and 125C]) was reacted with 2-(4-carboxymethyl-phenoxy-2-methyl-propionic acid tert-butyl ester (example 124A]) to give 2-(4-{[4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylcarbamoyl]-methyl}-phenoxy)-2-methyl-propionic acid tert-butyl ester, which was subsequently cleaved with trifluoroacetic acid to yield the title compound as yellow solid.
