반응 단계
(S)-2-Aminomethylpyrrolidine-1-carboxylic acid tert-butyl ester (0.3 g), 6-chloronicotinonitrile (0.21 g), potassium carbonate (0.41 g) and diisopropylethylamine (0.78 ml) were heated in xylene at 130° C. for 26 h, cooled and the mixture filtered through kieselguhr. The filtrate was evaporated and the residue chromatographed on silica gel, eluting with ethyl acetate-hexane mixtures to afford the title compound (0.2 g). Mass Spectrum (API+): Found 303 (MH+). C16H22N4O2 requires 302.
