実験手順
A solution of 3-methyl-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]butan-1-ol (6.61 g, 0.0244 mol) in DCM (300 mL) at 0° C. was treated with TEA (3.74 mL, 0.0268 mol), followed by methanesulfonyl chloride (2.07 mL, 0.0268 mol). The reaction was stirred for 1 hour, and was then concentrated in vacuo. The crude residue was purified by flash column chromatography to afford the desired product (4.9 g, 57%).
