2-Amino-4,6-dimethylpyridine → HCID 12821987, compound

Participants

Reaction Steps

To 1.2 g of 2-amino-4,6-dimethylpyridine in 30 ml of methylene chloride at ambient temperature was added dropwise, with stirring 2.4 g of methyl 2-isocyanatosulfonylbenzoate. After stirring for one hour at room temperature a solid precipitated from the mixture. Filtration yielded 1.8 g of a crystalline white solid which melted at 181°-182° C. and showed absorption peaks by infrared spectroscopy at 1750, 1700, 1630 and 1580 cm-1. The nuclear magnetic resonance spectrum (60 mc) showed peaks at 7-8.6 δ (multiplet) for o-substituted benzene, 4.36 δ (singlet) for OCH3 and 2.76, 2.7 δ (singlets) for the two methyl groups on the pyridine ring.
