The title compound was prepared according to the procedure of Example 216, with the modification that cyclooctanecarboxaldehyde (prepared from cyclooctanone according to the procedure given in Example 205, steps a and b) was used in step d instead of cyclohexanecarboxaldehyde and 5-amino-2-methyl-benzoic acid benzyl ester replaced 3-amino-benzoic acid benzyl ester in step f. 1H NMR (300 MHz, d6-DMSO) 12.40 (1H, br s), 12.10 (1H, br s), 9.55 (1H, br s), 8.29 (1H, s), 7.78 (1H, d), 7.20 (1H, d), 4.78 (2H, s), 2.96 (1H, m), 2.45 (3H, s), 2.10-1.53 (29H, m). The acid was converted to the N-methyl-D-glucamine salt and lyophilised from water/dioxan. Found: C, 61.55; H, 8.31; N, 7.60%; C38H58N4O9.1.5 H2O requires: C, 61.52; H, 8.28; N, 7.55%.
