Procedure

36 mg of N-[2-amino-5-(4-chloro-phenyl)-pyridin-3-yl]-3-(6-amino-4-methyl-pyridin-2-yl)-propionamide (compound A9) are treated with 2 g polyphosphoric acid at 125° C. for 24 h. Subsequent workup according to the procedure described herein for example A6 yields 6 mg of the title compound as a viscous oil after chromatography (dichloromethane/methanol 8:1). ESI-MS: 364.4/366.4 (MH+, 100%/36%). TLC: Rf=0.30 (dichloromethane/methanol 8:1).
