Participants

Reaction Steps

To a solution of 0.315 g (0.66 mmol) of 5-methyl-6-(4-pyrrolidin-1-yl-piperidine-1-carbonyl)-3-(3-trifluoromethyl-phenyl)-pyridine-2-carboxylic acid methyl ester (example 45) in 10 ml of THF/MeOH 1:1 were added 1.32 ml of lithium hydroxide (1 molar in H2O) and the reaction mixture was stirred at RT for 28 hours. Then, the solvents were evaporated and the residue was dissolved in H2O/CH2Cl2, neutralized with the help of hydrochloric acid and solid NaHCO3 and then extracted four times with CH2Cl2/2-propanol 3:1; the organic phases were dried over magnesium sulfate, filtered and evaporated, to give 0.188 g (62%) of the title compound as off-white solid. MS: 462.3 (MH+).
