実験手順

To a solution of 2-((1-(tert-butoxycarbonyl)piperidin-4-yl)amino)isonicotinic acid (150 g, 0.47 mol) in DCM (1500 mL) was added HATU (178 g, 0.47 mol) and TEA (47 g, 0.47 mol) at 20° C., then the mixture was stirred at the temperature for 2 h. (S)-1-amino-3-(3,4-dihydroisoquinolin-2(1H)-yl)propan-2-ol (113 g, 0.55 mol) was added to the solution, and the mixture was stirred at 20° C. for another 16 h, at which time TLC showed the completion of the reaction. The mixture washed with water (200 mL) and the combined organic phases were dried and concentrated. The residue was purified by flash chromatography (EtOAc˜DCM:MeOH=10:1) to give the title compound as yellowish oil. Four batches were run in parallel and produced a combined product weight of 510 g, yield: 53.2%. LCMS (m/z): 510.2 [M+H]+.
