Vorschrift

To the mixture of rel-1-[(3R,4R)-4-methyl-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one-(100 mg) and 2,4-dichloropyrimidine (82 mg) in ethanol (2 mL), triethylamine (75 mg) was added at ambient temperature. Then After the mixture was stirred at ambient temperature for 17 hours, water (10 mL) was added. The resulting precipitate was collected, to afford rel-1-[(3R,4R)-1-(2-chloro-4-pyrimidinyl)-4-methyl-3-piperidinyl]-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one (65 mg) as yellow powder. From NMR, it was found that the obtained powder was mixture of regioisomer (4:1).
