Pyridine 1-oxides acetamido

The infrared spectra of 2-, 3-, and 4-acetamido- and 2- and 3-benzamido-pyridine 1-oxides show bands characteristic of the 2-, 3-, or 4-substituted pyridine 1-oxide and of the —NHCOCH3...

Alkylpyrazines with other substituents have been oxidized to carboxylic acids as follows 2-acetamido-6-methylpyrazine was oxidized in aqueous magnesium sulfate with potassium permanganate to 2-acetamido-6aqueous potassium permanganate at room temperature to 2-carboxy-3-chloropyrazine, which was also obtained by oxidation of 2-chloro-3-methylpyrazine with selenium dioxide in boiling aqueous pyridine (947). Oxidations of 2-methoxy-3-methyl-... 

Ethylene oxide added to an ice-cold suspension of diethyl acetamido-(5-amino-3-indolylmethyl) malonate in methanol containing p-toluenesulfonic acid, and stirred 18 hrs. at room temp. diethyl acetamido-[5-bis-(2-hydroxyethyl)-amino-3-indolylmethyl] malonate (Y 99%) dissolved in pyridine, treated with methanesulfonyl chloride, and heated 20 min. in an oil bath at 80-90° after the exothermic reaction has subsided -> diethyl acetamido- [5-bis- (2-chlorethyl) -amino-3-indolylmethyl]malonate (Y 40-50%).—Other chlorodehydroxylation methods were not successful.
