実験手順

A solution of tert-butyl 5-chloro-3′,6′-dihydro-2′H-[2,4′]bipyridine-1′-carboxylate (50 mg) in chloroform (2.4 ml) was mixed with hydrogen chloride (4N in dioxane; 0.8 ml) and the mixture was concentrated after 13 hours. This resulted in the product with the molecular weight of 194.67 (C10H11ClN2); MS (ESI): 195 (M+H+).
