実験手順

In a similar manner to that described in Example 17 4-(4-chloro-3-piperidinomethylphenoxy)butyronitrile was prepared by the reaction of 2-chloro-5-hydroxybenzaldehyde (1.379 g), piperidine (1.8 ml) and sodium borohydride (0.33 g) in absolute ethanol (10 ml) to produce N-(2-chloro-5-hydroxybenzyl)piperidine which was then reacted with 4-bromobutyronitrile to yield the above-mentioned product.
