実験手順
672 mg of N-(2-amino-5-iodo-pyridin-3-yl)-3-[4-methyl-6-(trityl-amino)-pyridin-2-yl]-propion-amide (compound B9) are dissolved in 13 ml of aqueous acetic acid (50% strength) and heated at 80° C. for 4 h. Subsequent workup according to the procedure described herein for example B5 yields 116 mg of the title compound as an oil after chromatography on silica gel (eluent: dichloromethane/methanol 8:1). ESI-MS: 398.0 (MH+). TLC: Rf=0.32 (dichloromethane/methanol 8:1).
