| titleOfInvention | A process for preparation of 4-amino-1-isobutyl-1h-imidazo[4,5-c]-quinoline (imiquimod) |
| abstract | A process for preparation of imiquimod comprising oxidation of 1-Isobutyl-1H-imidazo quinoline quinoline (II) afforded 1-Isobutyl-lH- imidazo-[4,5-c]-quinoline-5-N-oxide (III) which is isolated in pure form as its hydrochloride salt (IV) followed by conversion to 4-chloro derivative(V) and conversion to corresponding 4-iodo derivative (VI) which is a new intermediate. This new intermediate is convened to imiquimod (VIII) and purified via its novel maleate salt. |
