Versuchsvorschrift
(Trans)-4-((3-chloropyrazin-2-yl)methylcarbamoyl)cyclohexyl acetate (2.8 g) was transformed into (trans)-4-(8-chloroimidazo[1,5-a]pyrazin-3-yl)cyclohexyl acetate (2.2 g) using the procedure described in example 1 step 1b using a reaction temperature of 60° C. for 16 hours. Reaction of the latter compound (2.6 g) yielded (trans)-4-(8-methylimidazo[1,5-a]pyrazin-3-yl)cyclohexyl acetate (1.6 g) using the procedure described in example 2 step 2d.
