Synthesis
GENERAL STEPS: 6-methoxyindole (33 mg) was dissolved in N,N-dimethylformamide (0.04 mL), and this solution was then slowly added dropwise to a pre-cooled mixture of N,N-dimethylformamide (0.07 mL) and phosphorous triclosan (0.07 mL) at 0°C. The reaction was carried out by stirring for 2.5 hours at room temperature. After the dropwise addition was completed, the reaction mixture was stirred for 2.5 hours at room temperature. Upon completion of the reaction, 6-methoxyindole-3-carboxaldehyde was isolated in 98% yield by appropriate post-treatment steps.
