Versuchsvorschrift

6-Chloronicotinic acid chloride (25.0 g, 137.8 mmol, 1 eq) was dissolved in 2-methyl-THF (328.0 g). A solution of 1-cyclobutyl-[1,4]diazepane (prepared as in Example 13 above, 24.1 g, 147.8 mmol, 1.05 eq) in 2-methyl-THF (164.0 g) was then added to the reaction mixture, while maintaining the temperature of the reaction mixture at less than 35° C. (about 45 min-1.5 hours). The resulting suspension was stirred at room temperature for 16 hours, then cooled to about 0-5° C. and maintained at 0° C. for 2 hours. The title compound was isolated by filtration, washed with 2-methyl-THF (2×45.0 g), then dried in vacuo at 60° C., to yield the title compound as a white solid.
