الإجراء التجريبي

To a solution of 3-(2,6-dichloro-3,5-dimethoxy-phenyl)-1-methyl-1-[6-(2-nitro-phenylamino)-pyrimidin-4-yl]-urea (50 g, 0.1 mmol) in THF (10 mL) and MeOH (10 mL) was added Raney-Ni (suspension in water) at room temperature, the resulting mixture was stirred for 2 hours under hydrogen atmosphere. The reaction was filtered and concentrated to obtain the title compound (38 mg, yield: 82%), which was used directly in the next step. 1H NMR (400 MHz, CDCl3) δ 3.28 (s, 3H), 3.85 (s, 2H), 3.94 (s, 6H), 5.86 (s, 1H), 6.52 (s, 1H), 6.78-6.87 (m, 3H), 7.16-7.20 (m, 2H), 8.39 (s, 1H), 12.62 (s, 1H); MS (ESI): 463 [M+H]+.
