実験手順
To a microwave vial was charged with (3R,9aS)-tert-butyl 3-(2-chloro-3-cyano-4-fluorophenyl)hexahydropyrazino[2,1-c][1,4]oxazine-8(1H)-carboxylate (30 mg, 0.076 mmol), potassium cyclopropyltrifluoroborate (16.8 mg, 0.114 mmol), Pd(OAc)2 (1.7 mg, 7.58 μmol), X-Phos (7.2 mg, 0.015 mmol), and potassium carbonate (31.4 mg, 0.227 mmol). CPME (0.4 mL) and Water (40 μL) were added, and the reaction mixture was degassed with N2 and heated at 100° C. for 24 h. The reaction mixture was filtered to give the crude product, which was purified by prep-TLC (1000 μm, 5% MeOH/DCM) to give the title compound: LC/MS: [(M+1-56)]+=346.3.
