Yield: 90%
Reaction Conditions:
Stage #1:indole;oxalyl dichloride in diethyl ether at 0 - 20; for 6 h;
Stage #2:methanol in diethyl ether at 0; for 0.5 h;
Steps:
Preparation of compound methyl 2-(1H-indol-3-yl)-2-oxoacetate (1)
In a reaction flask,7 g ( 60 mmol ) indole and 300 mL of dry diethyl ether were add, and 16.1 mL of oxalyl chloride was added dropwise to the reaction solution at 0 °C. The reaction was continued for 6 h at room temperature to form a yellow suspension. It was further placed at 0° C, 12 mL of methanol was added dropwise to the reaction, and the mixture was stirred for 30 min. The resulting mixture was filtered and washed with ice ether to finally obtain a yellow solid 1 ( 10.93 g , 90% yield).
