Procedure

2-(4-nitrophenoxy)ethoxyacetic acid methyl ester 59 (1 g, 3.9 mmol) was dissolved in anhydrous ethyl acetate (20 ml), palladium carbon (10%, 0.1 g) added and the mixture stirred under a hydrogen atm. using a balloon for 30 min. Catalyst was filtered, filtrate concentrated, hexane (3 ml) added, and the solid filtered to give 60 (625 mg, 70.9%) as a light brown powder. M.p: 51-52.5° C.
