Reaction Steps

A solution of {3-[2-Amino-4-chloro-7-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-7H-pyrrolo [2,3-d]pyrimidin-5-yl]-prop-2-ynyl}-carbamic acid tert-butyl ester (see previous example, 22 mg) in DCM (3 mL) was treated with TFA (0.6 mL) at rt for 15 min. Evaporation, work-up (DCM/sat. aq. NaHCO3), drying (Na2SO4), and evaporation gave the title compound as an oil. tR=3.85 min. 1H NMR (CDCl3) δ 8.24 (s, 1H), 7.06 (s, 1H), 5.32 (s, 2H), 5.02 (s, 2H), 3.75 (s, 3H), 2.27 (s, 3H), 2.20 (s, 3H).
