Versuchsvorschrift

A mixture of N-(3-(6-chloro-5-cyano-4-(4-phenoxyphenyl)pyridin-2-yl)phenyl)acetamide (25 mg, 0.057 mmol) and 35% aqueous hydrazine (0.051 mL, 0.568 mmol) in 2-propanol (1.5 mL) was heated to 160° C. under microwave for 1 h then cooled to room temperature. Purification with reverse phase HPLC (Sunfire S10 30×250 mm column), eluting with 60-90% solvent B (10% methanol-90% water-0.1% TFA) in solvent A (90% methanol-10% water-0.1% TFA), gave Example 25 as the faster eluting peak (18 mg, 41% yield, yellow solid) and Example 24 as the slower eluting peak (3 mg, 8% yield, yellow solid).
