Procedure
The title compound was prepared from 470 mg of 1-t-butyloxycarbonyl-4-(1-bromo-formylmethyl)piperidine (from Piperidine 1, Step C) and 277 mg of 2-amino-4-tert-butyl pyridine (from Step A) in 12 mL ethanol using a procedure analogous to that described in Piperidine 1, Step D to provide the title compound as a solid.
