実験手順

To a solution of (S)-6-chloro-N-(3-(3,4-dihydroisoquinolin-2(1H)-yl)-2-hydroxypropyl) pyrimi dine-4-carboxamide (240 g, 0.69 mol) in i-PrOH (2.5 L) was added 1-(3-amino azetidin-1-yl)ethanone (120 g) and TEA (100 g). After addition, the solution was heated at 60° C. for 16 h, at which time LCMS showed completion of the reaction. 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 420 g, 90% purity. This crude was further purified on preparative HPLC to give the title compound (330 g, >98% purity, free base form). 1H NMR (400 MHz, MeOD-d4) 8.27 (s, 1H), 7.12-6.98 (m, 5H), 4.71 (s, 1H), 4.54 (m, 1H), 4.32 (m, 1H), 4.06 (m, 2H), 3.88 (m, 1H), 3.70 (s, 2H), 3.53-3.50 (m, 2H), 2.91-2.83 (m, 4H), 2.65 (m, 2H), 1.88 (s, 3H); LCMS (m/z): 425.2 [M+H]+
