Methylation of heterocyclic compounds containing NH, SH and/or OH groups by means of N,N-dimethylformamide dimethyl acetal Methylations of heterocyclic systems, such as benzimidazole, naphth[2,3-c]imidazole, imidazo[4,5-c]-pyridine, purine, pyridine, pyrimidine, pyridazine and s-triazolo[4,3-b...
N,N-Dimethylformamide dimethyl acetal (CAS NO.4637-24-5) is also called as Dimethylformamide-dimethylacetal ; 1,1-Dimethoxytrimethylamine ; Methanamine, 1,1-dimethoxy-N,N-dimethyl- . 4.4 Toxicity LD50 orally in Rabbit: > 5000 mg/kg5
Secondary amines are formylated by dimethylformamide dimethylacetal, contradicting recent reports on the ethylation of secondary amines by this reagent. This explains why a single derivative is obtained regardless of the alkyl acetal that is used. These formyl derivatives, also formed by reaction with...
