Breant, P.; Marsais, F.; Queguiner, G. published an article in 1983, the title of the article was Regioselective lithiation of 3-pyridylsulfonic acid derivatives: a convenient route to various new 4-substituted 3-pyridylsulfonamides.Computed Properties of 636-73-7 And the article contains the following content:
Pyridinesulfonamides I [NR2 = piperidino, morpholino, pyrrolidino; R1 = C(OH)Ph2, (un)substituted α-hydroxybenzyl] were prepared from lithiopyridines II and the resp. carbonyl compounds Amide III was treated at -60° with (Me2CH)2NH and BuLi in Et2O, PhCHO in Et2O was added at -70°, and the mixture was stirred 2 h at -70° to give I [NR2 = piperidino, R1 = PhCH(OH)]. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Computed Properties of 636-73-7
The Article related to addition lithiopyridinesulfonamide benzaldehyde, pyridinesulfonamide hydroxybenzyl, hydroxybenzylpyridinesulfonamide, Heterocyclic Compounds (One Hetero Atom): Pyridines and other aspects.Computed Properties of 636-73-7
