2-BROMO-1-CHLORO-4-(TRIFLUOROMETHOXY)BENZENE

General procedure: A mixture of (4-iodophenyl)(methyl)sulfane (Compound 4A) (500 mg, 2 mmol), 4-bromophenylboronic acid (400 mg, 2 mmol), Na2CCh (636 mg, 6 mmol), and Pd(PPh3)4 (115 mg, 0.1 mmol) in toluene/EtOH/H20 (20/10/4 mL) was stirred at 80 C under nitrogen overnight The mixture was concentrated under reduced pressure. The residue was purified with flash column chromatography on silica gel (ethyl acetate in petroleum ether, 10% v/v) to afford Compound 4B. LC-MS (ESI) m/z: non-ionizable compound under routine conditions used. - NMR (CDCb, 500 MHz): d (ppm) 2.52 (s, 3H), 7.32 (d, J= 8.5 Hz, 2H), 7.43 (d, J= 8.5 Hz, 2H), 7.48 (d, J= 8.5 Hz, 2H), 7.55 (d, J= 8.5 Hz, 2H).General procedure: To a solution of Compound 6A (138 mg, 0.32 mmol) in tolunen (4 mL) was added N-methylpiperazine (160 mg, 1.6 mmol), t-BuONa (61 mg, 0.64 mmol), Pd2(dba)3 (29 mg, 0.032 mmol), and Xantphos (37 mg, 0.064 mmol) and heated in a microwave oven at 120 C for 2 hours. The mixture was concentrated and purified by reverse phase column chromatography to afford Compound 6B. LC-MS (ESI) m/z: 440 [M+H]+.A mixture of
