실험 절차

To a solution of ethyl 3-[(2-ethoxy-5-fluoropyrimidin-4-yl)amino]-6,6-dimethyl-5,6-dihydropyrrolo[3,4-c]pyrazole-1(4H)-carboxylate dihydrochloride (120 mg, 0.27 mmol) in 15 mL THF containing diisopropylethyl amine (0.23 mL, 4 eq) was added a 5 mL THF suspension of 4-fluoro-1-methylpiperidine-4-carbonyl chloride (128 mg, 2.6 eq). After heating for 5 hours at 65° C., the reaction was concentrated to dryness and carried on without further purification. To a solution of ethyl 3-[(2-ethoxy-5-fluoropyrimidin-4-yl)amino]-5-[(4-fluoro-1-methylpiperidin-4-yl)carbonyl]-6,6-dimethyl-5,6-dihydropyrrolo[3,4-c]pyrazole-1(4H)-carboxylate in methanol was added 2 mL of a 10% sodium hydroxide solution in methanol. After removing the solvent in vacuo, the residue was purified as in Example K1 above. See Table 1 below for NMR data.
