実験手順

(S)-tert-Butyl-3-aminopyrrolidine-1-carboxylate (50 g, 192.5 mmol) was added to 6-benzyl-4-chloro-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidine (39.440 g, 211.8 mmol) in NMP (200 mL) solution followed by the addition of K2CO3 (39.9 g, 288.8 mmol). The mixture was heated to 120° C. for 20 h. The mixture was allowed to cool, partitioned between water (300 mL) and ethylacetate (500 mL). the bottom aqueous phase was discarded and the upper organic phase was washed with brine (150 mL) and concentrated in vacuo to provide crude (S)-3-(6-benzyl-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-4-ylamino)-pyrrolidine-1-carboxylic acid tert-butyl ester as a pale yellow foam (76.44 g, 97% yield).
