Reaction Conditions

Reaction Steps

To a 500 ml round bottomed flask equipped with a magnetic stir bar under N2 atmosphere was charged methyl 3-cyclopropyl-3-oxopropanoate 1 (39.2 g, 276 mmol), MeI (17.2 ml, 276 mmol) and K2CO3 (57.2 g, 414 mmol). The mixture was agitated at 25 °C for 16 h. The reaction mixture was diluted with Et2O (100 ml) and filtered. The solids were rinsed with Et2O (100 ml) and the filtrate was concentrated to a crude oil. The crude oil was purified by normal phase column chromatography to give methyl 3-cyclopropyl-2-methyl-3-oxopropanoate 2 in 79% yield.
