Procedure
To a solution of 6,8-dichloro-1-methylspiro[benzo[e]isoxazolo[5,4-c]azepine-4,1′-cyclopropane] (61.9 mg, 0.211 mmol) in toluene (22 mL) was added 4-fluorophenylboronic acid (37 mg, 0.264 mmol) and Pd(Ph3P)4 (11.22 mg, 9.71 μmol). The reaction was evacuated and purged with N2 (g) (3×), followed by addition of aqueous Na2CO3 (211 μl, 0.422 mmol, 2 M). The reaction was heated to 82° C. for 15 min at which time LC-MS analysis indicated complete conversion to desired product. The reaction mixture was cooled to room temperature and diluted with water. The aqueous layer was extracted with EtOAc (3×) and the combined organic extracts were dried over Na2SO4, and concentrated in vacuo. The crude product was purified on Biotage system (5% EtOAc:95% Hexanes to 10% EtOAc:90% Hexanes). The product 8-chloro-6-(4-fluorophenyl)-1-methylspiro[benzo[e]isoxazolo[5,4-c]azepine-4,1′-cyclopropane] (62 mg, 0.176 mmol, 83% yield) was obtained as a white crystals. LC/MS m/z 353 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ 7.81-7.77 (m, 1H), 7.75-7.71 (m, 1H), 7.45-7.38 (m, 2H), 7.19-7.26 (m, 3H), 2.52 (s, 3H), 1.29 (s, 4H).
