Abstract
Regioselective N-alkylation of 4-chloro-2-(methylthio)-7H-pyrrolo[2,3-d]pyrimidine (1) with ethyl 3-bromopropionate under liquid-liquid phase transfer reaction conditions and further saponification of the ester function under formation of compound 3b is described. Subsequent SNAr substitution of the 4-chloro substituent by an amino function [...] Read more.
Regioselective N-alkylation of 4-chloro-2-(methylthio)-7H-pyrrolo[2,3-d]pyrimidine (1) with ethyl 3-bromopropionate under liquid-liquid phase transfer reaction conditions and further saponification of the ester function under formation of compound 3b is described. Subsequent SNAr substitution of the 4-chloro substituent by an amino function and reductive removal of the 2-methylthio group of 3b gives, via 4a, the title compound 4b. Full article
