Procedure

Triethylamine (16 uL, 0.12 mmol) was added to a mixture of 4-(4-methylpiperazin-1-yl)-6-(1,2,3,4-tetrahydroisoquinolin-7-yl)pyrimidin-2-amine trihydrochloride (50 mg, 0.1 mmol), (5-bromopyridin-3-yl)acetic acid (30.0 mg, 0.14 mmol) (Lancaster, Cat. #L13579), and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (56 mg, 0.13 mmol) in N,N-dimethylformate (1.5 mL). The reaction mixture was stirred at r.t. overnight. The mixture was diluted with water, and extracted with ethyl acetate (3×10 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on a silica gel column with MeOH in dichloromethane (0-10%) to afford the desired product. Analytic LCMS (M+H)+: m/z=521.95/523.95.
