4-(1-Pyrrolidinyl)piperidine → [5-methyl-3-pyrimidin-5-yl-1-(3-trifluoromethyl-phenyl)-1H-pyrazol-4-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone

Reaction Steps

In analogy to the procedure described in Example 160E], a mixture of 5-methyl-3-pyrimidin-5-yl-1-(3-trifluoromethyl-phenyl)-1H-pyrazole-4-carboxylic acid and 1-(4-bromo-3-trifluoromethyl-phenyl)-5-methyl-3-pyrimidin-5-yl-1H-pyrazole-4-carboxylic acid and 4-(1-pyrrolidinyl)piperidine gave a mixture of the title compounds. Purification by reversed phase HPLC (MeCN:H2O) afforded [1-(4-bromo-3-trifluoromethyl-phenyl)-5-methyl-3-pyrimidin-5-yl-1H-pyrazol-4-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone (Example 174) and [5-methyl-3-pyrimidin-5-yl-1-(3-trifluoromethyl-phenyl)-1H-pyrazol-4-yl]-(4-pyrrolidin-1-yl-piperidin-1-yl)-methanone as a white solid (20%). MS: 485.4 (MH+).
