実験手順: But-3-enylamine (1.0 mole), the diethyl acetal of 3-bromopropionaldehyde (1.0 mole) and methanol (100 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. The reaction mixture is heated at reflux with stirring for a period of about 6 hours. After this time the reaction mixture is cooled to room temperature and sodium hydroxide (20 grams) is added. The reaction mixture is then stirred for an additional period of about 16 hours. The mixture is then filtered and the filtrate is distilled to yield the desired product the diethyl acetal of 3-but-3-enylaminopropionaldehyde. equipped with a mechanical stirrer thermometer and reflux condenser The reaction mixture is heated at reflux The reaction mixture is then stirred for an additional period of about 16 hours The mixture is then filtered the filtrate is distilled

実験手順: To a suspension of 1-chloro-4-(3-fluorophenyl)-6-methoxyisoquinoline-3-carbonitrile (150 mg) in 15 mL isopropanol was added to 6 mL of a 0.81 M solution of 4-amino-1-butene. The mixture was heated to reflux for 4 days, then cooled to room temp and partitioned between EtOAc and saturated aqueous sodium bicarbonate. The organic solutions were washed with brine (1×), dried over MgSO4, and concentrated. Flash chromatography (3% to 50% EtOAc in hexanes) provided 146 mg of 1-(but-3-enylamino)-4-(3-fluorophenyl)-6-methoxyisoquinoline-3-carbonitrile as a tan solid. The mixture was heated to reflux for 4 days partitioned between EtOAc and saturated aqueous sodium bicarbonate The organic solutions were washed with brine (1×) dried over MgSO4 concentrated
