Versuchsvorschrift

Chlorosulphonic acid (70 μl, 1.0 mmol) was added dropwise to solution of 2-anilino-4-(2-formyl-1-isopropylimidazol-5-yl)pyrimidine (Example 10; 75 mg, 0.24 mmol) in thionyl chloride (2 ml) cooled at 0° C. and the mixture was stirred at 0° C. for 10 minutes then heated at 90° C. for 90 minutes. The volatiles were removed by evaporation and the residue was dried under high vacuum (<2 mmHg) for 1 hour. The resulting solid was placed under nitrogen and a solution of 2-methoxyethylamine (100 μl, 0.5 mmol) and diethylmethylamine (0.5 ml, 7.5 mmol) in MeOH (1.5 ml) added. The mixture was stirred for 30 minutes and the volatiles were evaporated in vacuo. The residue was purified by chromatography eluting with DCM/MeOH (98:2) to give the title compound (26 mg, 24%) as glassy solid. NMR: 1.53 (d, 6H) 2.86 (q, 2H) 3.17 (s, 3H) 3.28 (t, 2H) 5.65 (m, H) 7.3 (t, 1H) 7.50 (t, 1H) 7.71 (d, 2H) 7.83 (s, 1H) 7.89 (d, 2H) 8.68 (d, 1H) 9.81 (s, 1H) 10.11 (s, 1H).
