Procedure

To a solution of propionic acid (12 mg, 0.1 mmol) in DMF (0.6 mL) was added HATU (92 mg, 0.2 mmol) and the reaction mixture was stirred at room temperature for 30 min. To it was added N4-(3-aminophenyl)-N6-(4-phenoxyphenyl)pyrimidine-4,6-diamine (60 mg, 0.1 mmol) followed by DIPEA (41 mg, 0.3 mmol) and the reaction mixture was stirred at this temperature for 16 h. It was concentrated under reduced pressure. The residue was diluted with CH2Cl2 (5 mL) and was washed with NaHCO3 solution (2 mL), water (2 mL), and brine (2 mL). Drying over Na2SO4 followed by concentration under reduced pressure offered a residue that was purified by column chromatography (SiO2, 230-400, chloroform/methanol:9/1) to give N-(3-(6-(4-phenoxyphenylamino)pyrimidin-4-ylamino)phenyl)propionamide (IR-10) as a brown solid. 1H NMR (DMSO-d6) δ ppm: 1.06 (t, J=7.56 Hz, 3H), 2.30 (q, J=7.48 Hz, 2H), 6.13 (s, 1H), 6.94-6.99 (m, 4H), 7.08 (t, J=7.36 Hz, 1H), 7.16-7.24 (m, 3H), 7.36 (t, J=7.44 Hz, 2H), 7.54 (d, J=8.88 Hz, 2H), 7.81 (s, 1H), 8.23 (s, 1H), 9.12 (s, 2H), 9.81 (s, 1H); LCMS: m/e 426.3 (M+1).
