実験手順

A mixture of 2-((2-methylbenzo[d]oxazol-5-yl)methyl)isoindoline-1,3-dione (200 mg; 0.68 mmol), and hydrazine monohydrate (715 mg; 21.89 mmol) in EtOH (30 ml) was refluxed, under nitrogen, for 4 h. After cooling to rt, the mixture was filtered, and the filtrate was concentrated to dryness under reduced pressure affording (2-methylbenzo[d]oxazol-5-yl)methanamine as an orange oil. LC-MS (conditions D): tR=0.50 min.; [M+H]+: 163.07 g/mol.
