A mixture of 3.0 g (22.0 mmol) of 3,4-dihydro-5-hydroxy-1(2H)-isoquinolinone and 6.7 g (48.5 mmol) of potassium carbonate in 100 ml of ethanol was refluxed for one hour. Then 10.9 ml (100 mmol) of 1-bromo-3-chloropropanol was added and refluxing continued for five hours. The solution was cooled and concentrated. The residue was dissolved in chloroform, filtered and concentrated to provide 4.45 g (85%) of 5-(3-chloropropoxy)-3,4-dihydro-1(2H)-isoquinolinone; mp 131.5°-133°.
