実験手順
To a solution of 2-(2-hydroxy-3,3-dimethyl-butoxy)-isoindole-1,3-dione (1.47 g, 5.60 mmol) in dichloromethane (20 mL) cooled to 0° C. was added methylhydrazine (0.31 mL, 5.90 mmol). The white suspension was allowed to stir for 16 hours at room temperature. Diethyl ether (50 mL) was added and the solids were removed by filtration. The filtrate was concentrated, diluted with diethyl ether and the solids were removed by filtration. This procedure was repeated twice more and the final filtrate was concentrated to provide the desired product as a yellow liquid (0.643 g, 86%). 1H NMR (400 MHz, CDCl3) δ 4.87 (br s, 2H), 3.85 (q, 1H), 3.58 (q, 2H), 0.93 (s, 9H).
