Versuchsvorschrift
To a solution of 3-methoxybenzamide (1.5 g, 9.9 mmol) in toluene (15 mL) was added 1-chloropropan-2-one (1.37 g, 14.9 mmol), and the mixture was stirred at reflux for 16 h. The mixture was cooled and concentrated to give crude product, which was purified via silica gel chromatography eluted with ethyl acetate/petroleum ether (1:5) to give 2-(3-methoxyphenyl)-4-methyloxazole (1.21 g, 64.6% yield) as yellow syrup. LCMS MH+ 190.
