实验步骤: A test tube (25×150 mm) containing a stirring bar and 2-amino-indan-2-carboxylic acid ethyl ester (0.53 g, 2.58 mmol) is charged with dry DCM (3 mL). Stirring is initiated. After dissolution, the DIPEA (1.50 mL, 8.6 mmol) and 4-dimethylaminopyridine (2 mg, 17 μmol) are added. A solution of 2-chloro-6-methylbenzoyl chloride (5.8 mmol) in dry DCM (4 mL), as prepared above, is added to the reaction tube. After stirring for 18 h, tlc analysis (silica, 10% CH3OH in DCM) indicates complete consumption of the amine. The reaction mixture is diluted with DCM (10 mL) and washed with 5% aqueous HCl (2×5 mL) and brine (5 mL), dried over MgSO4 filtered and evaporated by pumping to constant weight gives 1.07 g of light brown solid. This material is purified by chromatography (silica, 2% to 20% EtOAc in DCM) on the ISCO Companion using a 40 g cartridge. Fractions 6-10 are combined, evaporated and pumped to yield a constant weight 550 mg of white amorphous solid.

实验步骤: A round bottom flask containing the 2-chloro-6-methyl-benzoic acid (1.5 g, 8.79 mmol) and a stirring bar is charged with dry DCM (10 mL). Stirring is initiated. After several min, a solution of thionyl chloride (in DCM (2M), 6.6 mL, 13.2 mmol) is added via syringe. 2 drops of DMF are then added. The reaction immediately began to bubble gently. After 2 h bubbling ceases. After 3 h, the solvent is removed from the reaction mixture in vacuo. The oily residue is redissolved in DCM (6 mL) and the solvent once again removed in vacuo. The residue is dissolved in dry DCM (6 mL) and used without further purification in the next reaction sequence.
