Reaction Steps

A solution of ethyl bromoacetate (7.19 ml, 63 mmol) and 4-amino-o-cresol (7.39 g, 60 mmol) in dry acetonitrile (420 ml) was treated at 15° C. with Cs2CO3 (42.03 g, 129 mmol) and stirred at RT for 2 h. Additional ethyl bromoacetate (0.33 ml, 3 mmol) was added and after 4 h, the mixture was filtered, washed with acetonitrile and evaporated. The residue was suspended in CH2Cl2, filtered and evaporated to give 13.34 g (quantitative) of (4-amino-2-methyl-phenoxy)-acetic acid ethyl ester as a green oil, MS: 210 (MH+).
