Versuchsvorschrift
Methyl 4-ethyl-8-nitro-1,2,3,4-tetrahydro-6-quinoxalinecarboxylate (D210) was prepared from methyl 8-nitro-1,2,3,4-tetrahydro-6-quinoxalinecarboxylate (D209) in an analogous manner to the process described for Ester 35 (B35) using acetaldehyde instead of propionaldehyde. [M+H]+=266.3, RT=3.07 min.
