Reaction Conditions

Reaction Steps

110 ml of a solution containing 10 g of 5-chloro-1H-indole-3-carboxylic acid (commercial) in DMF is added dropwise to a mixture of 4.50 g of NaH (60% in oil) in 400 ml of DMF at −10° C. After it returns to RT, it is stirred for 1 hour. The reaction mixture is cooled to −20° C. 4.86 ml of methyl bromoacetate is added dropwise, it is returned to RT for a period of 5 hours and is stirred for 15 hours. The reaction mixture is added to 1 L of EtOAc/1N HCl mixture, the organic phase is collected and the aqueous phase is extracted with EtOAc. The organic phases are combined, washed with water and with brine, then dried over Na2SO4 and evaporated to dryness. 8.9 g of the expected compound is obtained in the form of a white powder.
