Procedure
To a stirred solution of Intermediate 339B (100 mg, 0.255 mmol) in THF (10 mL) was added DIPEA (0.222 mL, 1.273 mmol) followed by 2,2,2-trifluoroethyl trifluoromethanesulfonate (118 mg, 0.509 mmol) and stirred at RT for 16 h. The reaction mixture was quenched with a 10% aqueous solution of NaHCO3 and extracted with EtOAc (2×20 mL) The combined organic layer was dried over Na2SO4, filtered and the filtrate evaporated. The crude compound was purified by preparative HPLC to afford Compound 339 as an off-white solid (15 mg, 12%). HPLC retention times 10.73 min. and 11.90 min (Methods C and D). MS(ES): m/z=475 [M+H]+; 1H NMR (300 MHz, DMSO-d6) δ ppm 7.84 (dd, J=7.37, 2.08 Hz, 1H), 7.62-7.72 (m, 1H), 7.41-7.50 (m, 1H), 7.36 (br. s., 1H), 7.27 (d, J=6.80 Hz, 1H), 7.18 (br. s., 1H), 4.73 (s, 2H) 4.19-4.31 (m, 1H), 4.06-4.17 (m, 2H), 3.84 (d, J=5.67 Hz, 2H), 3.57-3.69 (m, 2H), 3.09-3.23 (m, 4H).
