To a solution of Compound 1B (4.32 g, 13.79 mmol) in THF (100 mL) was added Et3N (3.84 mL, 27.6 mmol) followed by (bromomethyl)benzene (1.64 mL, 13.8 mmol). Upon completion of addition, the reaction mixture was stirred at rt overnight. After this time, the reaction mixture was quenched with saturated aqueous NH4Cl (50 mL), and then extracted with EtOAc (3×50 mL). The combined organic layers were washed with brine (40 mL) and dried (MgSO4). The solvent was removed and the resulting residue was recrystallized from MeOH to give Compound 14A as a white solid (2.12 g, 5.26 mmol, 38% yield). LC/MS (m/z)=404 (M+H)+.
