To amino(3-chlorophenyl)acetic acid (5.Og; 26.95mmol) suspended in methanol (30ml) and stirred at ice-bath temperature under argon was added dropwise thionyl chloride (30ml) over 30min. After stirring for a further 2h at 50C and at room temperature for 16h, the reaction solution was evaporated under reduced pressure. Trituration of the residue with diethylether afforded the title compound as a ca. 1 :1 mixture with amino(3- chlorophenyl)acetic acid (6.16g).
