Procedure
To 80 mg of 4-({2-[1-(2-fluorobenzyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazol-3-yl]-5-methoxypyrimidin-4-yl}amino)nicotinonitrile 2-1-7 (0.181 mmol, 1.00 eq.) were given at rt with caution 0.28 mL of sulfuric acid. The mixture was stirred for 3 days at rt. Then the reaction mixture was dropped into ice water and set with aqueous 2M sodium hydroxide solution to an alkaline pH. The suspension was filtrated and the resulted solid was dried at 65° C. to provide 86 mg (0.18 mmol, 83%) of the analytically pure target compound.
