Sodium Methoxide → N-(5-Methoxy-2-nitrophenyl)-S-methyl-L-cysteine

関与物質

反応手順

27 g of N-(5-fluoro-2-nitrophenyl)-S-methyl-L-cysteine (0.1 mol) from Example 1 are dissolved in 150 ml of absolute methanol in a four-necked flask, and 14.4 g of 95% sodium methoxide (0.25 mmol) are added in portions, within the space of 20 minutes and under argon, to this solution while stirring well and while cooling by means of an ice bath. The mixture is then heated to reflux for 2 hours while stirring. TLC monitoring then indicates that the reaction is complete.
