Reaction Conditions

Reaction Steps

A cooled (0° C.) stirred solution of (R)-3-amino-pyrrolidine-1-carboxylic acid tert-butyl ester (1.0 g, 5.36 mmol) and TEA (1.5 ml, 11.0 mmol) in THF (10 ml) is treated dropwise over 1 minute with pyridine-4 carbonyl chloride hydrochloride (0.935 g, 5.25 mmol). After 5 minutes, the reaction mixture is allowed to warm to room temperature and stirred overnight. The resulting mixture is diluted with EtOAc and washed twice with saturated sodium bicarbonate solution followed by brine. The organic portion is dried (MgSO4) and concentrated in vacuo. The crude product is purified by recrystallisation from EtOAc/iso-hexane to afford the title product. [MH+ 292].
