Procedure

Triethylamine (40 uL, 0.29 mmol) was added to a mixture of 4-(4-methylpiperazin-1-yl)-6-(1,2,3,4-tetrahydroisoquinolin-7-yl)pyrimidin-2-amine HCl salt (25 mg, 0.058 mmol), [1-(tert-butoxycarbonyl)piperidin-4-yl]acetic acid (17 mg, 0.069 mmol) (AstaTech Cat. #66860), and benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (28 mg, 0.063 mmol) in N,N-dimethylformamide (0.8 mL). The 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 (25 mg, 79%). Analytic LCMS (M+H)+: m/z=550.3.
