The reaction of 2-aminonicotinic acid with ethyl chloroform-phorinanone 6 was allowed to react with the tetracarbonyl ate, followed by alkylation with NaH/MeI and decarboxyla- norbornadiene derivatives of chromium (0) and molybdetion with methylamine, led to N- methyl-2-(methylamino) ni-num (0). The &-substituted tetracarbonyl complexes 12 and cotinamide (3). Treatment of 3 with PC13 in the presence of 13 were formed. In the ...
