- Production Method of KW-3196
-
KW-3196 (CAS NO.: 134186-21-3), with its systematic name of L-Iditol, 1,4:3,6-dianhydro-2-deoxy-2-(4-(3-pyridinylcarbonyl)-1-piperazinyl)-, 5-nitrate, could be produced through many synthetic methods.
Following is one of the synthesis routes: 1,4:3,6-dianhydro-D-glucitol 5-methanesulfonate (I) (1) with piperazine (II) afforded (III), which is nitrated with fuming HNO3 to give the nitrate ester (IV). Nicotynoylation of compound (IV) gives KW-3196.
