, (2011/10/05)

The present invention relates to compounds and methods which may be useful as inhibitors of H1R and/or H4R for the treatment or prevention of inflammatory, autoimmune, allergic, and ocular diseases.

A convenient synthesis of the potent mutagen 3,4,8-trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine.

Grivas

, p. 213 - 217 (2007/10/02)

The highly mutagenic title compound (4,8-DiMeIQx) was synthesized in 13% overall yield from 2-fluoro-5-nitrotoluene in eight operations. The average operation yield was 83%. The reaction sequence used gave, in addition to the title compound, the isomer 3,4,7-trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine (4,7-DiMeIQx).
