HCID 133952001-Methoxy-4-(pent-4-en-1-yl)benzene

Procedure

This compound was prepared as in Example 35a using 4-methoxyphenethyl magnesium bromide prepared from 4-methoxyphenethyl bromide and magnesium turnings. The crude oil isolated after work-up was distilled to give the title compound (b.p. 65° C., 0.3 mm.Hg), as a colourless oil.
