Reaction Steps

To a mixture of 4-[1-(1-methyl-2-piperazin-1-ylethyl)-1H-pyrazol-4-yl]-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine (0.21 g, 0.48 mmol) and DIPEA (0.26 mL, 0.0015 mol) in DCM (5 mL) was added 1-methyl-1H-pyrazole-3-sulfonyl chloride (0.14 g, 0.78 mmol) in portions at 0° C. The reaction mixture was stirred at RT overnight, quenched with water, and extracted with DCM. The organic layers were dried over MgSO4, concentrated and purified on silica gel (eluting with 0-5% MeOH in DCM) to give the desired product. LCMS calculated for C26H40N9O3SSi(M+H)+: m/z=586.3; Found: 586.4.
