Participants

Reaction Steps

To a solution of methyl (2R)-2-(3-{3-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-methoxy-6-methylphenyl}azetidin-1-yl)propanoate (chiral intermediate from example 156 step 2) (13 mg, 0.027 mmol) in acetonitrile (0.6 mL) and water (0.2 mL) was added lithium hydroxide (2.4 mg, 0.10 mmol). The reaction mixture was stirred at room temperature overnight. The reaction solution was diluted with ethyl acetate and 1 M HCl solution. The organic layer was separated and dried over Na2SO4, filtered and concentrated to give the desired product (10.2 mg, 83%). LCMS calculated for C22H28ClN6O3 (M+H)+: m/z=459.2; Found: 459.1.
