Reaction Steps
Prepared according to the method described in Example 66. (1S,2R)-[4′-(2-Hydroxy-1-methyl-4-pyridin-3-yl-butoxy)-biphenyl-4-yl]-acetic acid (Example 55, 0.07 g),pyrrolidine (0.014 g), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.038 g) and 1-hydroxybenzotriazole (0.027 g) were dissolved in dimethylformamide (2 ml) and stirred for 16 hours at room temperature. The dimethylformamide was removed by vacuum distillation, the residue was dissolved in dichloromethane, filtered and purified by normal-phase HPLC eluting with a gradient of 0-10% ethanol in dichloromethane to give the title compound as a glass (0.068 g).
