YieldReaction ConditionsOperation in experiment
30% With hydrogenchloride; water; In 1,4-dioxane; at 100℃; for 16h; Example 97-methyl-2-propyl-3H-benzimidazole-5-carboxylic acid (I1 R1 = CH3, R2 = /7-C3H7,R3 = COOH)The mixture of 7-methyl-2-propyl-3H-benzoimidazole-5-carbonitrile (250 mg, 1 mmol, 1.0 eq.), aqueous hydrochloric acid (36%, 2.5 ml_, 29 mmol, 2.3 eq.) in 1 ,4-dioxane (2.5 ml_) was heated to 100 0C for 16 h. After removal of volatiles, the concentrate was diluted with methanol, and decolorized with activated carbon to give a white solid. Yield: 85 mg (30%). The spectral data of this product were identical to that of commercial product:1H NMR (400 MHz, DMSO-d6): delta 12.42 (s, 1 H), 7.82 (s, 1 H), 7.56 (s, 1 H), 2.80 (t, J= 7.4 Hz, 2H), 2.50 (s, 3H), 1.79 (qd, J= 7.4 Hz, J = 7.32 Hz, 2H), 0.94 (t, J= 7.32 Hz, 3H). 13C NMR (100 MHz, DMSO-d6): delta 168.6, 157.5, 124.1 , 123.3, 31.0, 21.4, 17.1 , 14.2.
