Reaction Steps

1.03 g (25.8 mmol) of sodium hydroxide were added to a solution of 715 mg (2.6 mmol) of (+/−)-ethyl (4-nitrophenyl)(cyclopentyl)acetate in 6 ml of THF/methanol (1:1), and the mixture was stirred at RT overnight. The reaction mixture was then poured into water, neutralized with 1 N hydrochloric acid and extracted with ethyl acetate. The organic phase was dried over sodium sulphate and concentrated. The residue was taken up in 80 ml of diethyl ether, and 250 ml of petroleum ether were added. The precipitated solid was filtered off with suction and washed with petroleum ether. The product obtained in this manner was purified further by preparative HPLC. This gave 89.5 mg (14% of theory) of the title compound.
