YieldReaction ConditionsOperation in experiment
99.7% With pyridine; In N,N-dimethyl-formamide; at 50℃; for 6h; 1H-<strong>[1072-84-0]imidazole-4-carboxylic acid</strong>(5.0 g, 44.6 mmol) and triphenylchloromethane (13.8 g, 49.1 mmol)It was added to a mixture of 50 ml of DMF and 2.5 ml of pyridine. After the addition, the temperature is raised to 50 ° C for 6 h.The reaction was detected by HPLC. Post-treatment: The system is cooled, and the reaction system is slowly added to 100 ml of water.The gray solid precipitated, and the suspension was stirred for 1 hour and then filtered.The filter cake was washed with a small amount of water, dried for 30 min, and dried under vacuum at 50 ° C to obtain 15.8 g of a gray solid.Yield: 99.7percent.
95% With pyridine; In N,N-dimethyl-formamide; at 20℃; 1-(Triphenylmethyl)-1H-<strong>[1072-84-0]imidazole-4-carboxylic acid</strong> was prepared as described in J. Med. Chem. 2001, 44, 1268. 1 H-lmidazole-4-carboxylic acid (0.50 g, 4.5 mmol) and trityl chloride (1.35 g, 4.9 mmol) were added to a solution of DMF (30 ml.) and pyridine (15 ml.) and stirred overnight. Water and EtOAc were added. The layers were separated and the aqueous layer extracted with EtOAc (2 x 50 ml_). The organic extracts were combined, washed with water and brine, dried over Na2SO4, filtered and evaporated. The oil was triturated with EtOAc to afford the title compound (1.5 g, 95percent) as a white solid. 1H NMR (400 MHz, DMSO-d6): delta ppm 12.40 (br. s., 1 H), 7.42 (t, 9 H), 7.17 - 7.35 (m, 2 H), 7.10 (d, 6 H). MS: m/z 1 11 (M-243).
79% With pyridine; In N,N-dimethyl-formamide; at 20℃; Example 6; To a RT solution of 1H-<strong>[1072-84-0]imidazole-4-carboxylic acid</strong> (1.12 g, 9.99 mmol) in pyridine (15 mL) and DMF (30 mL) was added triphenylmethyl chloride (3.06 g, 11.0 mmol). The reaction mixture was stirred at RT overnight, then was partitioned between EtOAc (500 mL) and H2O (50 mL). The organic phase was washed with H2O (20 mL), 10percent citric acid (20 mL) and brine (5 mL), dried (MgSO4) and concentrated in vacuo. The residue was triturated with EtOAc to afford 1-trityl-1H-<strong>[1072-84-0]imidazole-4-carboxylic acid</strong> (2.78 g, 79percent yield) as a white solid. LCMS Method A (ESI, positive ion spectrum): (M+H)/z=not observed, tR=3.27 min.
