Procedure
A solution of (4-chloro-2-ethynyl-phenoxy)-acetic acid tert-butyl ester (Intermediate 3; 500 mg; 1.87 mmol) in MeOH (10 ml) was treated with an 1.25 N solution of HCl in methanol (1.5 ml). The solution was heated at 60° C. for 24 hours. The solvents were removed under reduced pressure to give the title compound as an oil which solidifies upon standing (445 mg, quantitative yield).
