Reaction Steps

5-(2-Adamantan-1-yl-ethyl)-2-cyclohexyl-1H-imidazole-4-carboxylic acid (Example 252) was reacted with 3-(3-amino-phenyl)-acrylic acid methyl ester (prepared in two steps from 3-nitro-benzaldehyde) according to the procedure of Example 20, step d. The methyl ester was hydrolysed using the same procedure as in Example 36, step d to afford the title compound. 1H NMR (300 MHz, d6-DMSO) 12.00 (1H, br s), 9.55 (1H, br s), 8.00 (1H, s), 7.86 (1H, m), 7.57 (1H, d), 7.36 (2H, m), 6.50 (1H, d), 2.89 (2H, m), 2.68 (1H, m), 1.94 (5H, br s), 1.80-1.51 (17H, m), 1.39-1.19 (5H, m). The acid was converted to the N-methyl-D-glucamine salt and lyophilised from water/dioxan. Found: C, 60.52; H, 8.50; N, 7.59%. C38H56N4O8.3.0 mols H2O requires: C, 60.78; H, 8.32; N, 7.46%.
