Participants

Reaction Steps

A mixture of 2-anilino 4-(2-formyl-1-propylimidazol-5-yl)pyrimidine (Method 118; 200 mg, 0.65 mmol) and dimethylamine (391 μl of 2M solution in THF, 0.78 mmol) in MeOH (6 ml) stirred for 3 hours at ambient temperature. Acetic acid (41 mg, 0.716 mmol) and sodium cyanoborohydride (45 mg, 0.716 mmol) were added and the mixture stirred for a further 18 hours. The volatiles were removed by evaporation and residue dissolved in EtOAc (7 ml). This solution was washed with saturated aqueous sodium hydrogen carbonate solution, water, and brine, then dried and the solvent removed by evaporation to give the title compound (210 mg, 96%) as a yellow foam. NMR: 0.62 (t, 6H), 1.50 (m, 2H), 2.23 (s, 6H), 3.60 (s, 2H), 4.56 (m, 2H), 6.98 (t, 1H), 7.10 (d, 1H), 7.28 (t, 2H), 7.62 (m, 3H), 8.39 (d, 1H), 9.39 (s, 1H); m/z 337.
