1-Bromopropane → HCID 63894506, compound

Participants

Reaction Steps

To a suspension of Mg (0.236 g, 9.83 mmol) in diethyl ether (10 mL), I2 (1 spatula) was added n-propyl bromide (0.72 g, 0.53 mL, 5.9 mmol) at room temperature. When iodine color disappeared, the remaining n-propyl bromide in ether was added to the reaction mixture and stirred at room temperature for 10 minutes. To this Grignard reagent, 5-bromo-2-fluorobenzaldehyde (1.00 g, 4.92 mmol) in ether was added under cold conditions and stirred at room temperature for 1 hour. The reaction mixture was quenched with NH4Cl solution and extracted with ether. The ether layer was dried over anhydrous Na2SO4, filtered and concentrated to afford 1-(5-bromo-2-fluoro-phenyl)-butan-1-ol (1.14 g, 92.6%). 1H NMR (CDCl3): δ 7.6 (m, 1H), 7.3-7.4 (m, 1H), 6.9 (t, 1H), 5.0 (brs, 1H), 2.0 (brs, 1H), 1.6-1.7 (m, 2H), 1.3-1.5 (m, 2H), 1.0 (t, 3H).
