Reaction Steps

In a manner analogous to the method described in examples 99, {4-[(4S,5R)-2-(6-tert-butyl-4-ethoxy-pyridin-3-yl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl]-piperazin-1-yl}-acetic acid hydrochloride (example 94) was coupled with 3-amino-propane-1,2-diol (Aldrich) to give the title compound as a mixture of diastereomers. HR-MS (ES, m/z) calculated for C38H49Cl2N6O5 [(M+H)+] 739.3136, observed 739.3139.
