実験手順
Add a solution of hydrazine (4.0 mL) in methanol (200 mL) to 2-(3-pyridin-4-yl-propyl)isoindole-1,3-dione (8.0 g, 30 mmol). After 48 hours, filter the mixture and concentrate the filtrate, triturate with methylene chloride (150 mL), and filter a second time. Perform the filtrate via flash chromatography on silica gel eluting with 80:18:2 CHCl3/MeOH/concentrated NH4OH) to afford the title compound as a yellow oil (3.42 g). MS: m/e=137 (MH+).
