ii. 27.9 g (0.1 mole) of triphenylmethyl chloride were dissolved in 250 ml of dimethylformamide, 14 g (0.21 mole) of sodium azide were added to this solution and the mixture was stirred for 10 hours at 80° C. After this time, a further 8.5 g (0.16 mole) of sodium azide were added and the mixture was again stirred for 8 hours at 80° C.
