Reaction Steps

To a stirred solution of 3-azidomethyl-4-hydroxy-piperidine-1-carboxylic acid tert-butyl ester (2 mmol, 0.512 g; Example 100) in DMF (5 mL) at 0° C. was added NaH (0.1 g, 60% dispersion in mineral oil) and continued stirring at 0° C. for 20 min. To this was Iodomethane (0.5 mL) and stirred at room temperature for 20 min. The volatiles were removed under reduced pressure, residue was dissolved in ethyl acetate (10 mL), washed with water, separated the organic layer, dried and concentrated under reduced pressure. The residue was purified by flash silica gel column chromatography to get 3-azidomethyl-4-methoxy-piperidine-1-carboxylic acid tert-butyl ester (0.41 g, 76% yield).
