실험 절차

A mixture of N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-phenyl]-4-piperazin-1-ylmethyl-benzamide (30 mg, 0.06 mmol, Zimmermann et al., Bioorg. Med. Chem. Lett. 1996, 6, 1221), diethyl 2-bromoethylphosphonate (30 μL, 0.12 mmol) and K2CO3 (20 mg, 0.16 mmol) in 2.5 mL of DMF was heated at 110° C. for 8 hours when most of the starting materials were consumed as judged by LCMS analysis. The solid material was filtered off. The filtrate was diluted with water and then extracted with EtOAc. The organic layer was dried over Na2SO4 and concentrated to dryness. The crude material was purified by silica gel chromatography using 10% MeOH/CH2Cl2 to provide 28 mg (55%) of the desired product. 1H NMR (300 MHz, CDCl3) δ 1.32 (t, 6H), 1.92-20.3 (m, 4H), 2.35 (s, 3H), 2.5 (bs, 6H), 2.64 (m, 2H), 3.56 (s, 2H), 4.05-4.14 (m, 4H), 7.07(s, 1H), 7.18 (d, 2H, J=5 Hz), 7.30 (dd, 1H, J=6, 8 Hz), 7.33-7.45 (m, 3H), 7.84 (d, 2H, J=8 Hz), 8.01 (s, 1H), 8.51 (dd, 2H, J=4, 9 Hz), 8.58 (d, 1H, J=2 Hz), 8.70 (dd, 1H, J=2, 5 Hz), 9.25 (s, 1H); 31P (121.4 MHz, CDCl3) δ 30.5; MS (m/z) 644 [M+H]+.
