Reaction Steps

To a mixture of [4-(2-amino-4-methyl-thiazol-5-yl)-pyrimidin-2-yl]-(3-nitro-phenyl)-amine (0.33 g, 1.0 mmol) and iodoethanol (0.44 g, 2.6 mmol) in dry DMF (2 mL) was added tert-butylimino-2-diethylamino-1,3-dimethylperhydro-1,3-diazaphosphorine (0.5 mL). The reaction mixture was heated at 124° C. for 20 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=14.30 min (Vydac 218TP54, 0-60% MeCN in 0.1% aq CF3COOH over 20 min, 1 mL/min, 25° C., purity>97%). 1H-NMR (CD3OD) δ: 3.30 (s, 3H, CH3), 3.91 (t, 2H, J=4.6 Hz, CH2), 4.25 (t, 2H, J=4.6 Hz, CH2), 7.21 (d, 1H, J=5.2 Hz, pyrimidinyl-H), 7.54 (m, 1H, Ph-H), 7.89 (m, 2H, Ph-H), 8.59 (d, 1H, J=5.2 Hz, pyrimidinyl-H), 8.90 (s, 1H, Ph-H).
