Yield	Reaction Conditions	Operation 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.

Yield	Reaction Conditions	Operation in experiment
37%		To a cooled solution (ice bath, 0-5 C) of the (aza)indole precursor (1 equivalent) in anhydrous THF (6 mL/mmol) is added tBuONa (2 M in THF, 1.2 equivalents), and the mixture is stirred for 25 min at the low temperature. Then the acylation reagent (preferentially: acyl chloride) (1.2 equiv.) is added and the reaction is aged overnight at room temperature. The reaction is quenched with saturated aqueous NH4Cl (provided in a commercial phase separator syringe) and the organic compound is extracted with CH2Cl2, washed with brine and water, dried over Na2SO4, filtered and concentrated in vacuo. The crude residue is subjected to flash chromatography (SiO2, ethyl acetate/hexane gradient) to afford the title compound as yellow oil, which usually stably crystallizes upon drying at high vacuum and subsequent storage at -20 C.

The reaction mixture was stirred at room temperature for 1 hour, at which time TLC showed formation of two new spots along with very little unreacted SM. The reaction was then diluted with ethyl acetate and water, the layers were separated and the organic layer was washed with water, brine, and dried over sodium sulfate. The organics were concentrated and the crude material was purified by column chromatography using (100-200 silica mesh, 0%-20% ethyl acetate/hexane) to get two fractions.
