Procedure

To a solution of tert-butyl 4-{2-[2-amino-6-(4-methylpiperazin-1-yl)pyrimidin-4-yl]-3-methyl-1,2,3,4-tetrahydroisoquinolin-7-yl}-3,6-dihydropyridine-1(2H)-carboxylate (Example 43, Step 1) (0.20 g, 0.38 mmol) in methanol (5 mL) was added palladium on carbon 10% wt. (20 mg) under an atmosphere of nitrogen. The mixture was vacuumed and re-charged with hydrogen three times, and stirred at r.t. for 48 h. The mixture was filtered. The filtrate was concentrated to afford the desired product which was directly used in next step reaction without further purification (200 mg, 99.61%). LCMS (M+H)+: m/z=522.3.
