Procedure

[3-(2,5-Dichloro-pyrimidin-4-ylamino)-phenyl]-acetonitrile was prepared from (3-Amino-phenyl)-acetonitrile and 2,4,5-Trichloro-pyrimidine in an analogous manner to Example 1223b. Title product was isolated as a beige solid (144 mg, 40%) after silica gel chromatography (ISCO 40 g 0-100% EtOAc in hexanes). 91% HPLC purity, MP=155-157, LCMS 279.11 (M+H), 1H-NMR (CDCl3, 400 MHz) δ 8.26 (s, 1H), 7.66 (d, J=8.6 Hz, 2H), 7.45 (dd, J=7.8 Hz, 1H), 7.28 (d, J=8.6 Hz, 1H), 7.17 (d, J=7.5 Hz, 1H), 3.82, s, 1H).
