4-Fluorophenol → HCID 54066592, compound

Participants

Reaction Steps

A mixture of 4-fluorophenol (41.3 g, 0.37 M), 4-fluorobenzaldehyde (45.7 g, 0.37 M) and K2CO3 (55 g) in 450 mL DMF was refluxed for 4 h, cooled, poured into ice water (1.5 L) to give a suspension. The mixture was filtered, washed with water, dried at 50° C. under vacuum to generate 78.3 g of the aldehyde 20 as a brownish solid. This compound was slurried in 2-propanol (1 L), then NaBH4 (14 g, 0.378 M) was added portionwise at room temperature. The resulting mixture was stirred at room temperature for 1 h, then concentrated. The residue was poured into water (1.5 L) to give a suspension. After filtration, the resulting solid, washed with water, dried at 50° C. under vacuum to give 76 g of 4-fluorophenoxybenzyl alcohol 26 as a yellowish crystal.
