Procedure

Trifluoroacetic Acid (2 mL, 0.02 mol) was added to a mixture of 4-[1-(3-methoxy-1-phenylpropyl)-1H-pyrazol-4-yl]-7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidine (80 mg, 0.0002 mol) in DCM (3 mL, 0.05 mol) at room temperature. The starting material was consumed after stirring for 2 hrs and the reaction solution was concentrated to remove the TFA. The crude reaction was diluted with methanol (3 mL, 0.07 mol) and was treated with ethylenediamine (0.3 mL, 0.004 mol) at room temperature. The reaction mixture was stirred for 18 hs and was concentrated and purified using HPLC on a C-18 column eluting with an ACN:water gradient containing 0.2% TFA, to give the title compound (43 mg, 60%) as a white amorphous solid. 1H NMR (400 MHz, CDCl3): δ8.9 (s, 1H), 8.8 (s, 1H), 8.4 (s, 1H), 7.8 (s, 1H), 7.4 (m, 1H), 7.3 (m, 5H), 7.2 (b, 1H), 5.7 (m, 1H), 3.3 (m, 1H), 3.2 (s, 3H), 2.7 (m, 1H), 2.4 (m, 1H). m/z=334 (M+1).
