A solution of [4-(2-amino-4-methyl-thiazol-5-yl)-pyrimidin-2-yl]-(3-nitro-phenyl)-amine (0.33 g, 1.0 mmol) in dry DMF (3 mL) was cooled on an ice-water bath. Chloroacetyl chloride (0.22 g, 2.0 mmol) and pyridine (80 μL) were added. After stirring at room temperature for 18 h, the product was isolated as a brown solid by preparative RP-HPLC (Vydac 218TP1022, 9 mL/min) using a gradient from 10-70% MeCN in 0.1% aq CF3COOH over 40 min. Anal. RP-HPLC: tR=20.62 min (Vydac 218TP54, 0-60% MeCN in 0.1% aq CF3COOH over 20 min, 1 mL/min, 25° C., purity >97%). 1H-NMR (DMSO-d6) δ: 2.45 (s, 3H, CH3), 4.12 (s, 2H, CH2), 7.03(d, 1H, J=5.2 Hz, pyrimidinyl-H), 7.42 (m, 1H, Ph-H), 7.63 (m, 1H, Ph-H), 8.01 (m, 1H, Ph-H), 8.41 (d, 1H, J=5.2 Hz, pyrimidinyl-H), 8.64 (s, 1H, Ph-H).
