Reaction Steps

In a similar manner to that described in Example 17 4-(4-nitro-3-piperidinomethylphenoxy)butyronitrile was prepared by the reaction of 5-hydroxy-2-nitrobenzaldehyde (10 g) with piperidine (12.3 ml) and sodium borohydride (2.7 g) in absolute ethanol (68 ml) to give N-(5-hydroxy-2-nitrobenzyl)piperidine which was then reacted with 4-bromobutyronitrile (4.1 ml) to give the above-mentioned product.
