Reaction Steps

Sodium hydride (21.24 mg, 0.53 mmol) was added to (S)-2-hydroxy-3-((S)-1-methoxypropan-2-yloxy)-N-(5-methylpyridin-2-yl)propanamide (Intermediate Y5) (95 mg, 0.35 mmol) in anhydrous THF (5 mL) at 0° C. under nitrogen. The resulting solution was stirred at 0° C. for 10 minutes and then 4-chloro-1-(2-chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidine (Intermediate B1) (122 mg, 0.46 mmol) in dry THF (2 mL) was added. The reaction was allowed to warm up to room temperature and stirred for 1 hour. The reaction mixture was diluted with ethyl acetate (20 mL), and washed sequentially with water (10 mL) and saturated brine (5 mL). The organic layer was dried (MgSO4) and evaporated. The crude product was purified by flash silica chromatography, eluting with 0-100% ethyl acetate in isohexane to afford the product (160 mg, 91%). 1H NMR (400 MHz, DMSO) δ 1.09 (d, 3H), 2.24 (s, 3H), 3.23 (s, 3H), 3.26-3.38 (m, 2H), 3.77-3.86 (m, 1H), 4.00-4.16 (m, 2H), 5.85-5.91 (m, 1H), 7.55-7.70 (m, 4H), 7.73-7.78 (m, 1H), 7.88 (d, 1H), 8.16-8.19 (m, 1H), 8.54 (s, 1H), 8.59 (s, 1H), 10.79 (s, 1H). m/z (ESI+) (M+H)+=497.20; HPLC tR=2.36 min.
