Reaction Steps
A mixture of 0.70 g of the phenol compound (prepared as described in Example 9), 0.30 g of sodium hydride (content 63%) and 14 ml of N,N-dimethylformamide was stirred at 100° C. for 20 minutes, and stirred with 0.64 g of ethyl bromoacetate at 70° C. for 2 hours. The reaction mixture was concentrated under reduced pressure, the residue was dissolved in water, and extracted with diethyl ether. The extract was washed with water, and a saturated aqueous solution of sodium chloride, dried over sodium sulphate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel using a 0.5% V/V solution of ethanol in chloroform as eluent to give 0.166 g of the title compound having the following physical characteristics:
