N-methyl-2-pyrrolidone → (4-hydroxy-piperidin-1-yl)-(4-{4-[7-(3-methanesulfonyl-propoxy)-1H-indazol-3-yl]-pyrimidin-2-ylamino}-cyclohexyl)-methanone

Participants

Reaction Steps

A mixture of (4-amino-cyclohexyl)-(4-hydroxy-piperidin-1-yl)-methanone (400 mg, 1.5 mmol), DIPEA (0.31 mL, 1.78 mmol) and NMP (1 mL) was stirred at RT for 1 h. Then, 7-(3-methanesulfonyl-propoxy)-3-(2-methanesulfinyl-pyrimidin-4-yl)-1H-indazole (200 mg, 0.5 mmol) was added to the mixture and stirred at 130° C. for 2.5 hours. The reaction mixture was then poured into water, and the precipitate was purified on a silica column using flash chromatography, eluting with hexane:EtOAc:MeOH 5:4.5:0.5 to yield (4-hydroxy-piperidin-1-yl)-(4-{4-[7-(3-methanesulfonyl-propoxy)-1H-indazol-3-yl]-pyrimidin-2-ylamino}-cyclohexyl)-methanone (Compound 308).
