2-Methyl-2-butanol → HCID 178526251、化合物

温度

67 °C

A mixture of 2-chloropyridine-N-oxide (16.6 g, 100 mmoles), 3-amino-1-propanol (15.3 ml, 200 mmoles), NaHCO3 (42 g, 0.5 mole), and tert-amyl alcohol (100 ml) was heated to reflux. After 23 hours, the reaction was cooled, diluted with CH2Cl2 (300 ml), and filtered to remove insoluble materials. The filtrate was concentrated to afford a brown oil. The oil was dried under vacuum overnight. Ether (100 ml) was added to give a brown solid. The ether was decanted and the solid was washed further with ether/acetonitrile (3/1). The resulting solid was heated at 67° C. under vacuum to give the desired product (13.5 g). 1H NMR was consistent with the proposed structure.
