実験手順
To [6-fluoro-5-(7H-pyrrolo[2,3-d]pyrimidin-5-ylmethyl)-pyridin-2-yl]-(4-methoxy-benzyl)-amine (P-0105, 4.5 g, 12.38 mmol) in 100 mL of dichloromethane, trifluoroacetic acid (95 mL, 1.238 mol) was added. The reaction was stirred at reflux for several hours, then concentrated under vacuum. The resulting material was taken up in ethyl acetate and poured into aqueous potassium carbonate. The resulting solid was filtered, washed with water, azeotroped from toluene and triturated with dichloromethane. The solid was isolated by filtration to provide the desired compound as a white solid (68, 2.8 g, 11.51 mmol, 93% yield).
