Conditions

Temperature: 130 °C

Procedure

The toluene solution from Stage 1 was mixed with triphenyl phosphine (1 g) and heated at 130° C. for 3 hours. After cooling, the solution was diluted with diethyl ether (5 cm3) and the title compound filtered off, washed with hexane (4×5 cm3) and dried by suction.
