実験手順

The solution of (S)-6-chloro-N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl)pyrimidine-4-carboxamide (190 g, 0.55 mmol) and 1-(4-aminopiperidin-1-yl)ethanone (78 g), Et3N (100 g, 1 mol) in i-PrOH (2000 mL) was stirred at 60° C. for 16 h, at which time LCMS showed completed conversion. The mixture was concentrated and the residue was purified by flash chromatography to give the crude product. Four batches were run in parallel and produced a combined crude product weight of 482 g. This crude was further purified on preparative HPLC to give the title compound (325 g, >98% purity, free base form). 1H NMR (400 MHz, MeOD-d4) 8.26 (s, 1H), 7.15-7.02 (m, 5H), 4.46 (m, 1H), 4.15-4.07 (m, 2H), 3.88 (m, 1H), 3.74 (s, 2H), 3.53 (m, 2H), 3.33 (m, 1H), 2.95-2.86 (m, 5H), 2.68 (m, 2H), 2.14-2.01 (m, 5H), 1.48-1.42 (m, 2H); LCMS (m/z): 453.3 [M+H]+
