1.13 g (19.4 mmoles) of prop-2-en-1-ol and 2.06 g (20.4 mmoles) of triethyl amine are added to the CH2Cl2 solution containing 5.34 g (18.5 mmoles) of 7-methyl-9-oxo-thioxanthene-3-carbonyl chloride. After approximately 1 hour at room temperature under stirring, the mixture is poured in water, the organic phase is separated and washed again with water. The organic phase is then separated, dehydrated and dried after purification on a flash column (SiO2— eluent: CH2O2). 3.02 g (52.6%) of a yellow solid with the following spectral properties are obtained:
