Reaction Steps

220 mg (0.36 mmol) of methyl 2-(3-{[6-amino-5-(trifluoroacetyl)pyridin-2-yl]amino}piperidin-1-yl)-6-(2,4-dichlorophenyl)pyridine-3-carboxylate hydrochloride (Example 8) were dissolved in 10 ml of 1,2-dimethoxyethane, and 4.4 ml of water were added. Then 43 mg (1.1 mmol) of sodium hydroxide were added and the mixture was stirred at RT for 30 min. For workup, 35 ml of 2 N hydrochloric acid were added and the precipitate which formed was filtered off with suction. 180 mg (75% of theory) of the product were obtained in solid form.
