Water → [1-(triphenylmethyl)-1H-imidazol-4-yl]methanol

Participants

Reaction Steps

4-hydroxymethylimidazole (4.53 g, 34 mmol) and triphenylmethylchloride (10.54 g, 38 mmol) were dissolved in DMF (50 mL). To this was added with stirring DIEA (13.46 g, 104 mmol) and the reaction mixture was stirred for 14 hrs. The reaction mixture was poured into water (750 mL) and stirred for about 30 min. The resulting solid was collected, washed with water (3×25 mL) and diisopropyl ether (3×25 mL), and dried in vacuo to yield 11.55 g (99%) of (1-trityl-1H-imidazol-4-yl)methanol. Purity (HPLC): 93%; retention time, 6.37 min.; column: Phenomenex Luna C18(2) (5 μm, 50×4.6 mm); gradient: 10% to 100% B in A over 10 min. at 1.25 mL/min. Solvent A: 0.1% TFA in water, Solvent B: 0.1% TFA in AcCN. ES-MS: (M+H)+=341.1.
