Journal of Heterocyclic Chemistry, 24, p. 1499, 1987 DOI: 10.1002/jhet.5570240602
Synthesis
Step1 :1-[(E)-2-(2-methoxy-6-nitrophenyl)vinyl]pyrrolidine: To a solution of 10 g of 1-methoxy-2-methy3-nitrobenzene in 100 ml of DMF are added 8.74 ml of N,N-dimethylformamide dimethyl acetal and 5.44 ml of pyrrolidine, and the mixture is then refluxed for 3 hours. The mixture is concentrated to half its volume under vacuum, the remaining mixture is poured into ether/water and extracted with ether, the organic phase is washed with saturated NaCl solution and dried over MgSO4 , and the solvent is evaporated off under vacuum. 1-[(E)-2-(2-methoxy-6-nitrophenyl)vinyl]pyrrolidine; yield 14.6 g.
Stpe 2 : synthesis of 4-Methoxyindole, A suspension of 150 ml of zinc powder in 500 ml of 0.5N HCl is stirred for 1 hour at room temperature. The suspension is ded by suction, washed with water to neutral pH, with anhydrous EtOH and then with ether, and dried. To a solution of 10 g of the compound from the preceding step in 46 ml of acetic acid are added, portionwise, 31.6 g of activated zinc, while keeping the temperature between 20 and 30°C using an ice bath. The reaction mixture is stirred at room temperature for 30 minutes, and is filtered. The filtrate is extracted with EtOAc, the organic phase is washed with NaHCO3 solution and with saturated NaCl solution, and dried over MgSO4 , and the solvent is evaporated off under vacuum. The residue is chromatographed on silica gel, eluting with a cyclohexane/EtOAc mixture in a gradient of from (98/2 v/v) to (95/5 v/v). 4-Methoxy- 1H-indole; yield 1.6 g.
