Procedure

119 g. (0.595 moles) of 4,5-methylenedioxy-1,2-benzenediacetonitrile was hydrogenated in 2.4 l. of ammonia-saturated ethanol at an initial pressure of 1,000 PSI and 100° C in the presence of 24 g of Raney nickel for 4 to 5 hours. The cooled autoclave contents were filtered to remove the nickel, the catalyst washed with 500 ml of hot ethanol, and the filtrate distilled at reduced pressure, leaving 120 g of dark gray oil. This oil was distilled in vacuo using a Claisen still head and several fractions were collected. The low boiling fractions contained the desired produ ct which upon purification yielded the above-named product, m.p. 82°-84°.
