The syntheses of various substituted azaindolines are described. Azaindolines were identified as potential key intermediates towards new PDE4 inhibitors. The experimental process involved the reaction of Ethyl 2-(3-aminopyridin-2-yl)acetate(cas: 295327-27-4Electric Literature of C9H12N2O2)
Ethyl 2-(3-aminopyridin-2-yl)acetate(cas: 295327-27-4) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.Electric Literature of C9H12N2O2
