Participants

Reaction Steps

5-(2-Adamantan-1-yl-ethyl)-2-(6,6-dimethyl-bicyclo[3.1.1]hept-2-en-2-yl)-1H-imidazole-4-carboxylic acid benzyl ester was prepared according to the procedure of Example 70, step a, with the modification that (1R)-(−)-myrtenal was used in instead of 2-dimethylamino-benzaldehyde. The benzyl ester was hydrolysed according to the procedure of Example 20, step c and the resulting 5-(2-adamantan-1-yl-ethyl)-2-(6,6-dimethyl-bicyclo[3.1.1]hept-2-en-2-yl)-1H-imidazole-4-carboxylic acid was reacted with 3-amino-benzoic acid methyl ester hydrochloride using essentially the same procedure as in Example 52, step a. Deprotection was carried out following essentially the procedure of Example 36, step d to afford the title compound. 1H NMR (300 MHz, d4-MeOH) 8.36 (1H, t), 7.90 (1H, ddd), 7.75 (1H, dt), 7.42 (1H, t), 6.30 (1H, m), 3.02 (1H, dt), 2.99 (2H, m), 2.57 (1H, m), 2.49 (2H, dd), 2.19 (1H, m), 1.95 (3H, s), 1.71 (6H, m), 1.60 (6H, d), 1.42 (2H, m), 1.40 (3H, s), 1.26 (1H, d), 0.90 (3H, s) was converted to the N-methyl-D-glucamine salt and lyophilised from water/dioxan. Found: C, 62.39; H, 7.98; N, 7.58%. C39H56N4O8.2.2 H2O requires: C, 62.55; H, 8.14; N, 7.48%.
