1,3-Dibromopropane → 1-(3-Bromopropoxy)-4-fluorobenzene

関与物質

反応手順

To a solution of 4-fluorophenol (0.0567 g, 0.506 mmol) in acetonitrile (4 mL) was added 1,3-dibromopropane (0.520 mL, 5.12 mmol) followed by Cs2CO3 (0.252 g, 0.774 mmol). The reaction mixture was stirred for 24 h and then concentrated under vacuum. The resulting residue was treated with H2O (4 mL) and extracted with DCM (8 mL). The organic layer was dried through a phase separator and concentrated under vacuum. The residue was taken up in DMSO and purified by preparatory HPLC (without TFA) to give the title compound (0.0173 g, 14.7%). EI-MS Rt (2.25 min).
