Reaction Steps

To a solution of 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 (60 mg) and sodium cyanide (38 mg) in DMSO (1 mL), 1,4-diazabicyclo[2.2.2]octane (5 mg) was added at ambient temperature. The temperature was raised to 80° C. and stirred for 7 hours. After cooling down to ambient temperature, water (15 mL) was added to the mixture and resulting precipitate was collected by filtration. The filtrate was purified by pre-packed column (chloroform:methanol=95:1 to 80:20) to afford rel-4-[(3R,4R)-4-methyl-3-(2-oxo-3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-1(2H)-yl)-1-piperidinyl]-2-pyrimidinecarbonitrile (41 mg) as white powder.
