Procedure

(2-Meth yl-5-nitro-phenyl)-[4-(5-pyrrolidin-1-yl-pyridin-3-yl)-pyrimidin-2-yl]-amine 9 is prepared by mixing 8 (0.40 g, 1.04 mmol), pyrrolidine (3.12 mmol), K3PO4 (0.44 g, 2.08 mmol), CuI (38.5 mg, 0.10 mmol) and L-proline amino acid (48.1 mg, 0.21 mmol) in DMSO (8 ml) and heating at 160° C. in a microwave oven for 20 min. The cooled mixture is partitioned between water and ethyl acetate. The organic layer is separated, and the aqueous layer is extracted with ethyl acetate. The combined organic layers are washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue is dissolved in DMSO (4 mL) and purified with HPLC to afford pure product 9. 1H NMR (400 MHz, d-CDCl3) δ 9.23 (d, J=2.4 Hz, 1H), 8.63 (d, J=5.2 Hz, 1H), 8.58 (s, 1H), 8.10 (s, 1H), 8.04 (s, 1H), 7.90 (dd, J=8.4, 2.4 Hz, 1H), 7.44 (s, 1H), 7.39 (d, J=8.4 Hz, 1H), 7.30 (d, J=5.2 Hz, 1H), 3.43-3.48 (m, 4H), 2.49 (s, 3H), 2.12-2.16 (m, 4H). LC/MS (m/z) (M+1)+: 377.2.
