Reaction Steps
To a solution of 2-(2,3-dihydro-benzofuran-2-ylmethyl)-isoindole-1,3-dione (0.97 g, 3.47 mmol) in MeOH (15 mL) and CH2Cl2 (5 mL) is added hydrazine (0.55 mL, 17.4 mmol). After 20 h at rt, the mixture is filtered off and the filtrate is concentrated. The residue is diluted with water (50 mL), and extracted with CH2Cl2 (2×50 mL). The extracts are dried (MgSO4), filtered, and concentrated to afford C-(2,3-dihydro-benzofuran-2-yl)-methylamine, which is used for a next step without further purification. LCMS: RT=1.25 minutes; MS: 150 (M+H).
