Participants

Reaction Steps

In a manner similar to the procedure described in Example B except that a 100 milliliter three-necked Morton flask was used, 10.0 grams (42.0 mmol) of ethyl 3-[(4-methoxyphenyl)amino]-3-oxopropanoate, 14.54 grams (105.0 mmol) of anhydrous potassium carbonate, 30 milliliters of dimethylformamide and 7.9 grams (42.0 mmol) of 1,2-dibromoethane were reacted for a period of 12 days to give 5.74 grams (22.0 mol) of ethyl 1-(4-methoxyphenylaminocarbonyl)cyclopropanecarboxylate as a colorless solid having a melting point of 89.5° C.-91.0° C. The total yield was 56 percent. NMR analysis of the product indicated the following:
