Versuchsvorschrift

2-(2-Methyl-1H-indol-3-yl)acetic acid (11.7 g, 61.84 mmol) was weighed and added into 100 mL methanol. Concentrated hydrochloric acid 0.7 mL was added dropwise. It was reacted at 70° C. for 4 hours, cooled, rotate evaporated to dryness, extracted with ethyl acetate, washed twice with NaHCO3 aqueous solution. The organic phase was dried and rotate evaporated to dryness to obtain a red brown solid 11.4 g, at a yield of 90.7%.
