Reaction Steps

A 500 mL flask under a nitrogen atmosphere was charged with anhydrous methanol (150 mL), imidazole-4-carboxaldehyde (45.82 grams, 476 mmol) and decylamine (74.99 grams, 476 mmol) with stirring. Several drops of concentrated hydrochloric acid were added to the mixture and the mixture was allowed to reflux overnight under nitrogen. The mixture was taken up into ethyl acetate, washed with water and brine, dried with sodium sulfate, and evaporated to dryness. The crude product was dissolved in a 4:1 ratio of anhydrous THF and anhydrous MeOH and transferred to a hydrogenation reaction flask. To this solution was added 5 wt. % Pd/C (5 wt. %) and the resulting mixture was hydrogenated overnight at 30 psi H2. After hydrogenation was complete, the solution was filtered through Celite under vacuum to remove the Pd/C and the filtrate was evaporated to dryness. 1H NMR (CDCl3) δ 7.5-7.6 (1H), 6.8-6.9 (1H), 3.6-3.8 (2H), 2.6 (t, 2H), 1.5 (t, 2H), 1.2-1.4 (m, 14H), 0.8-0.9 (t, 3H).
