Conditions

Temperature
180 °C

Procedure

31 g of 1-Allyloxy-3-phenyl-7-nitro-naphthalene prepared in step (3) were gradually heated to 180° C. in 390 ml of decaline, the solution being stirred and maintained under nitrogen. The temperature of 180° C. was maintained for about 1 hour. After cooling, the crystals formed were washed with petroleum ether, filtered off and dried at 80° C. under reduced pressure.
