Page/Page column 83, (2010/11/30)
Compounds of formula (1): are disclosed, wherein V is CH2; W is S(O)m; m is the integer 0, 1 or 2; U is O, C(O), CR13R14 or NR15; where R13 is H, alkyl; R14 is H, OH, OR13 or OCOR13; R15 is H, alkyl, cycloalkyl, alkenyl, C(O)R13, C(O)OR13 or alkylaminocarbonyl; R1, R2, R3, R4, R5, R6, R7 and R8 are as defined herein. These compounds are inhibitor of tumor necrosis factor-alpha (TNF- ) and are useful as medicaments for the treatment and prevention of disorders caused by increased TNF- activity, in particular inflammations.

10-Chloroquinoxalinocinnoline readily undergoes methoxydechlorination when treated with sodium methoxide.The 1-, 2-, 3-, 4- and 9-chloro isomers are unreactive towards this reagent, but the 9,10-dichloro derivative undergoes substitution of both chlorines (the 10-position being much the more reactive).The 9- and 10-bromo analogues are both unreactive towards sodium methoxide, but the 9- and 10-fluoro analogues are both highly reactive, to the extent that it has not been possible even to isolate the 10-fluoro compound.Routes to 9- and 10-piperidinoquinoxalinocinnolines are described.
