実験手順

tert-Butyl 2-(5-bromo-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino)-7,8-dihydro-1,6-naphthyridine-6(5H)-carboxylate 158c (3.2 g, 7.4 mmol) was suspended in methylene chloride (20 mL), saturated hydrogen chloride in dioxane (20 mL) was added dropwise. The reaction mixture was stirred for 20 minutes and concentrated under reduced pressure to give 205a, which was used without further purification in the next step. LC/MS: m/z 336 (M+H)+
