Reaction Steps

Oxone (123 mg, 0.2 mmol) was added to a stirred solution of 4-[2-(ethylthiomethyl)-1-(propyl)imidazol-5-yl]-2-{4-[N-(2-ethoxyethyl)sulphamoyl]anilino}pyrimidine (Example 82; 70 mg, 0.14 mmol) in MeOH/acetone/water (15:5:3) (2 ml) at 0-4° C. The solution was allowed to warm to ambient temperature and stirred for 2 hr. The reaction mixture was diluted with water and extracted with EtOAc. The extracts were combined, washed with brine, dried (Na2SO4) and the volatiles removed by evaporation. The residue was purified by chromatography on silica gel eluting with DCM/MeOH (95:5) and the purified product triturated with ether to give the title compound (44 mg, 59%). NMR: 0.65 (t, 3H), 1.03 (t, 3H), 1.27 (t, 3H), 1.52 (m, 2H), 2.85 (q, 2H), 3.30 (m, 6H), 4.64 (t, 2H), 4 81 (s, 2H), 7.25 (d, 1H), 7.46 (t, 1H), 7.70 (d, 2H), 7.79 (s, 1H), 7.97 (d, 2H), 8.50 (d, 1H), 9.91 (s, 1H); m/z 537.
