Procedure

A mixture of a 60:40 mixture of the ethyl and methyl esters of 2-amino cyclohex-1-ene carboxylic acid (47.2g; 0.29 mole) and diethyl malonate (46.4g; 0.29 mole) were added to a solution of sodium (7.2g; 0.29 mole) in ethanol (145 ml) stirred at ca 110° C for 30 hrs. in an autoclave. The product was acidified with 5N HCl to pH 4.0 and diluted with water. The precipitated ester was filtered off and recrystallised from ethanol with charcoalisation, m.p. 236° -7° (d).
