Procedure

A mixture of ethyl 4-cyano-3,5-diethoxybenzoate (1.0 g, 3.8 mmol) and KOH (5.0 g, 89.3 mmol) in water (30 mL) was stirred at 130° C. overnight. The mixture was acidified with aqueous HCl (2M) until pH=5. Solvent removed in vacuo and used for next step directly without further purification.
