1-(3-chloropropyl)-4-fluorobenzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a CH3CN (60 mL) solution containing methyl (2R)-2-[(tert-butoxycarbonyl)amino]-3-mercapto-3-methylbutanoate (as described above) (1.51 g, 5.73 mmol, 1.0 eq) was added sodium tert-butoxide (716 mg, 7.45 mmol, 1.3 eq). The resulting pale yellow mixture was allowed to stir at RT for 10 min at which time 1-(3-chloropropyl)-4-fluorobenzene (as described above) (1.09 g, 6.3 mmol, 1.1 eq) was added. The resulting solution was allowed to stir at RT for 18 hr. The reaction was then quenched with a sat NH4Cl solution, poured into H2O, and extracted (2×) with EtOAc. The combined extracts were dried over MgSO4 and concentrated in vacuo and then purified via flash chromatography using 5:1 hexanes/EtOAc as the mobile phase. Isolated 700 mg (1.75 mmol, 31% yield). was added The reaction was then quenched with a sat NH4Cl solution poured into H2O extracted (2×) with EtOAc The combined extracts were dried over MgSO4 concentrated in vacuo purified via flash chromatography Isolated 700 mg (1.75 mmol, 31% yield)
