Reaction Steps
Method F This compound can be prepared from 5-(1-isopropyl-6-nitro-1H-indol-3-yl)-pyridine-2-carbonitrile (4, R1=i-Pr, R3=5-(2-cyanopyridine)) in a manner substantially similar to that described immediately above for 4-(6-amino-1-isopropyl-1H-indol-3-yl)-benzonitrile except Degussa type E101 NE/W 10% Palladium on activated carbon can be used instead of platinum (II) oxide in Method E. LRMS (API ES+)=277.0 (M+H).
