Procedure
E3 (67 mg, 0.11 mmol), cyclobutyl amine (14.7 μL, 0.17 mmol), and sodium triacetoxyborohydride (73 mg, 0.34 mmol) were stirred in dichloroethane at room temperature for 3 h. The reaction mixture was diluted with dichloromethane, then washed with saturated aqueous sodium bicarbonate and brine. It was dried over magnesium sulfate, filtered, concentrated in vacuo. Purified by chromatography (4% to 10% methanol with 0.1% ammonium hydroxide in dichloromethane), recovering 31 mg of E4.
