Reaction Conditions:

with hydrogenchloride;tin(ll) chloride in water at 80; for 4 h;

Steps:

1.1.2 1.1.2 Synthesis process of intermediate compound a3
First, stannous chloride dihydrate (250 mmol, 2 eq) was dissolved in 120 ml of concentrated hydrochloric acid.To be completely dissolved, the compound 2-(3-ethoxy-4-hydroxyphenyl)-2-hydroxyacetic acid (94 mmol, 1 eq) was added to a hydrochloric acid solution of stannous chloride dihydrate and reacted at 80 ° C for 4 h. The reaction was stopped, cooled to room temperature, and a white solid was precipitated and crystallised from distilled water to give 16.3 g of 2-(3-ethoxy-4-hydroxyphenyl)acetic acid as a white solid.
