3 g (7.7 mmol) of 2-[4-(2-chlorophenyl)-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-2-yl]ethane-1-carboxylic acid, 0.69 g (7.7 mmol) of 2-amino-2-methylpropan-1-ol, 2,35 g (23 mmol) of triethylamine and 4.8 g of carbon tetrachloride are stirred in 15 ml of pyridine/acetonitrile (1:1) at ambient temperature. Within 2 hours a solution of 6.2 g (23.6 mmol) of triphenylphosphine in 15 ml of the above pyridine/acetonitrile mixture is added dropwise to the mixture.
