On August 6, 1996, Suzuki, Masashi published a patent.Formula: C7H10N2 The title of the patent was Preparation of methylaminopyridine derivatives in high-yield. And the patent contained the following:
The title compounds (I; R = C1-4 alkyl, n = 1-2, X = NHMe) can be efficiently and economically produced by reaction of I (X = NH2, R, n = same as above) with a mixture of (HCO)2O and (AcO)2O or with HCO2H in the presence of (AcO)2O, followed by reduction of formyl group. I are useful intermediates in the production of drugs and pesticides. Thus, I (Rn = 4-Me and 6-Me, X = NH2) was reacted with HCO2H in the presence of (AcO)2O to give 85% I (Rn = 4-Me and 6-Me, X = NHCHO), which was reduced by LiAlH4 to give 97% I (Rn = 4-Me and 6-Me, X = NHMe). The experimental process involved the reaction of N,3-Dimethylpyridin-2-amine(cas: 156267-13-9).Formula: C7H10N2
