Methylamine → Methyl 6-(methylamino)-5-nitronicotinate

関与物質

反応手順

1.6 g (7.4 mmol) of methyl 6-chloro-5-nitronicotinate (see Bernie et al., J. Chem. Soc. 1951, 2590) were stirred in 20 mL of 40% aqueous methylamine solution at room temperature for 30 minutes. The reaction mixture was then diluted with ice water, the yellow precipitate formed was filtered off and dried. Yield: 1.2 g (80% of theory); Rf value: 0.66 (silica gel; ethyl acetate/ethanol/glacial acetic acid=90:5:5).
