Participants

Reaction Steps

A solution of 5.74 g (25.3 mmoles) of 140 and 50 mL of NH3 were hydrogenated with 2 g of Raney nickel in a steel autoclave at 100 bar H2 and 100° C. for 2 hours. The catalyst was filtered off with suction and the solution was evaporated and distilled using a bulb tube (boiling point: 135°-145° C. at 0.01 mbar): 5.02 g of 141 as a colorless oil (87% of the theoretical yield).
