Yield:99988-56-4 98%
Reaction Conditions:
Stage #1: 5-methoxylindole;oxalyl dichloride in diethyl ether at 0; for 1.5 h;
Stage #2: methanol in diethyl ether at 0; for 1 h;
Steps:
1.1 Example 1
In the first step, add 5-methoxyindole (1.00g, 6.80mmol) and diethyl ether (14mL) into a 100mL round bottom flask, add oxalyl chloride (0.68mL) dropwise at 0C, react for 1.5h and filter with suction , The solid obtained by suction filtration was added to a 100mL round-bottomed flask, and MeOH (60mL) was added at 0°C, reacted for 1h and then suction filtered to obtain compound 29, a yellow solid, with a yield of 98%.
