Versuchsvorschrift

Calcium carbonate (138 mg) and D-leucinamide•hydrochloride (83 mg) were added to a 1,4-dioxane (1 ml) solution containing 6-chloro-5-fluoro-2-(quinolin-6-ylamino)nicotinonitrile (30 mg), followed by reflux for 15 hours. The reaction mixture was cooled to room temperature, and water, sodium chloride, and ethyl acetate were added. The organic layer was collected and dried over anhydrous magnesium sulfate, and the solvent was distilled away under reduced pressure. Diisopropylether was added to the obtained residue, solid matter was collected by filtration, and a yellow solid of (2R)-2-(5-cyano-3-fluoro-6-(quinolin-6-ylamino)pyridin-2-ylamino)-4-methylpentanamide (33 mg) was thus obtained.
