Diethyl Ether → HCID 20547154, compound

Participants

Reaction Steps

A solution of 10 g of methyl methacrylate in 100 ml of ether is treated with an excess of ethereal diazomethane for about 16 hours. The ether is removed in vacuo to give 12.5 g of the title compound as an oil. Examination of the oil on thin layer chromatography silica gel plates using 40% ethyl acetate/hexane shows a single spot at Rf =0.34, visualized with phosphomolybdic acid plus heat. The oil has the following spectral characteristics: NMR(13C,CDCl3 ppm), 170.9(C-1), 94.1(C-2), 28.0(C-3), 77.1(C-4), 21.1(C-5), 52.3(C-6), IR(neat), 5.78μ(CO2CH3), 6.5μ(N=N). ##STR20##
