Potassium Carbonate → HCID 68029870, compound

Participants

Reaction Steps

To a soln. of 4-(2-methoxyphenyl)-1-methyl-1H-imidazole-5-carbaldehyde (78 mg, 0.361 mmol) in acetone (5 ml) and water (1 ml) was added potassium carbonate (100 mg, 0.721 mmol). After potassium was dissolved, KMnO4 (123 mg, 0.776 mmol) was added at r.t. The mixture was stirred for 24 hrs. LC/MS showed the completion. The mixture was filtered through celite, washed w/water. The actone was evaporated from the filtrate which was extracted with EtOAc (2×). The aq. layer was acidified w/HOAc to PH=5, reduced the volume to half volume, feezed and lyphilized to leave solid, which was purified by Pre-HPLC to afford the title compound (41 mg, 0.173 mmol, 48% yield). 1H-NMR (MeOD), δ: 8.06 (s, 1H), 7.41-7.36 (m, 2H), 7.05-6.99 (m, 2H), 3.98 (s, 3H), 3.80 (s, 3H).
