13.3 g (123 mmol) of benzyl alcohol and 4.7 g (31 mmol) of hydroxybenzotriazole are added to a solution of 6.0 g (31 mmol) of 6-butyl-2-oxo-1,2-dihydro-isonicotinic acid in 100 ml of DMF. The resulting clear solution is cooled to 0° C., followed by the addition of 7.0 g (34 mmol) of dicyclohexylcarbodiimide and 4.2 ml (31 mmol) of triethylamine. The mixture is allowed to thaw to 20° C., stirred for a further 2 hours and subjected to aqueous work-up. 6.8 g (77% of theory) of the title compound are obtained.
