実験手順

A solution of {5-[2-amino-4-chloro-7-(4-methoxy-3,5-dimethyl-pyridin-2-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]-pent-4-ynyl}-carbamic acid tert-butyl ester (see previous example, 33 mg) in DCM (1.0 mL) was treated with TFA (0.2 mL) at rt for 10 min. The reaction mixture was concentrated, taken in water (1.5 mL), washed with EtOAc (1.5 mL), made alkaline with sat. aq. NH4OH (0.5 mL), and back-extracted into EtOAc (25 mL). Washing (NH4OH 1M), drying (Na2SO4) and concetration affroded the title compound. tR=4.37 min. 1H NMR (CDCl3) δ 8.15 (s, 1H), 6.97 (s, 1H), 5.25 (s, 2H), 3.72 (s, 3H), 2.94 (m, 2H), 2.48 (t, 2H), 2.23 (s, 3H), 2.16 (s, 3H), 1.80 (quint., 2H).
