HCID 7757151-(4-methoxyphenyl)-1H-indole

Procedure

By the method of Preparation C43, p-bromoanisole (140 g, 0.75 mole), indole (60 g, 0.51 mole), K2CO3 (75 g, 0.54 mole) and Cu2Br2 (28 g, 0.1 mole) were converted to title product, purified by distillation, rather than chromatography, 67.7 g, b.p. 150-160/0.4-0.5 mm, which crystallized on storage in the refrigerator, m.p. 52°-54° C.
