Reaction Steps
In a similar manner to Example 12, methyl 4-[2-methyl-3-(4-thiocarbamoylbenzoyl)carbazoyl]phenoxyacetate (2.5 g) was reacted with iodomethane (15 ml) in acetone (150 ml) and the resultant product was treated with ammonium acetate (6.5 g), methanol (100 ml) and dichloromethane (100 ml). This yielded a crude yellow solid, which was triturated with methanol, collected and washed with methanol/dichloromethane, rather than crystallised, to give the title compound (1.3 g) as an off-white solid; m.p. 210° C. (decomposes); NMR Spectrum (DMSO-d6) 1.73 (3H, s), 3.20 (3H, s), 3.55 (3H, s), 4.76 (2H, s), 6.90 (2H, d), 7.53 (2H, d), 7.80 (4H, m), 8.50-11.0 (2H, br s); Mass Spectrum m/Z 385 (M+H)+ ; Elemental Analysis: calculated for C19H20N4O5. 1.0 CH3CO2H. 0.8 H2O: C, 55.0%; H, 5.6%; N, 12.2%; found: C, 55.0%; H, 5.4%; N, 11.8%.
