実験手順
The aldehyde (0.22 g) of Example 1 in ether (5 ml) is added to lithium aluminium hydride (0.08 g) in ether (5 ml), and the mixture stirred at 20° for 1 hour. After successive dropwise additions of water (80 l), 15% NaOH (80 l) and water (240 l), the resulting clear ether layer (+ washings) is evaporated to a residue of 4(Z-3-chloroallyl)benzyl alcohol yield 0.19 g (86%) nD20 1.5529.
