실험 절차

In a similar manner to that described in Example 17 2-chloro-3-hydroxybenzaldehyde (9 g) in absolute ethanol (60 ml) was treated with piperidine (11.7 ml) and sodium borohydride (2.2 g) to yield N-(2-chloro-3-hydroxybenzyl)piperidine. The piperidine thus prepared was reacted with 4-bromobutyronitrile to give 4-(2-chloro-3-piperidinomethylphenoxy)butyronitrile.
