YieldReaction ConditionsOperation in experiment
93% at 68℃; for 16 h; To a stirred solution of 2-(1H-indazol-3-yl)acetic acid (35-1) (4.86 g, 27.5 mmol) in Methanol (250 mL ) was added sulfuric acid (0.543 g, 5.53 mmol) and the reaction was refluxed at 68°C for 16 h. Reaction progress was monitored by TLC. The MeOH was evaporated to dryness and the residual gum was basified with saturated sodium bicarbonate solution and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulphate and evaporated in vacuo to yield methyl 2-(1H-indazol-3-yl)acetate (35-2) (4.90 g, 25.7 mmol, 93 percent) as a light brown solid.
77% for 14 h; Reflux General procedure: A solution of the (2-aza-)indoleacetic acid derivative (1 equivalent) in alcohol (preferentially methanol; 8.8 mL/mmol) containing 3 drops/mmol of concentrated sulfuric acid is refluxed overnight until the starting material is consumed. The progress of the conversion is monitored by TLC and/or LCMS. The reaction mixture is concentrated under reduced pressure to a low volume, and then diluted with ethyl acetate (5 mL/mmol). The organic layer is treated with water (2x3 mL/mmol) and 10percent sodium bicarbonate solution (3 mL). The ethyl acetate phase is collected, dried over sodium sulfate, concentrated and then kept at high vacuum to obtain the title compound as an amorphous solid.
