3-Hydroxybenzaldehyde → 3-Isopropoxybenzaldehyde

Participants

Reaction Steps

A mixture of commercially available 3-hydroxybenzaldehyde (3.000 g; 24.60 mmol), 2-iodopropane (12.528 g; 73.70 mmol), K2CO3 (6.790 g; 49.10 mmol), and Cs2CO3 (1.601 g; 4.91 mmol) in anh. DMF (60 ml) was stirred at rt, under nitrogen, for 17 h. Et2O was added and the organic layer was washed with water, dried over anh. MgSO4, filtered, and concentrated to dryness under reduced pressure affording 3-isopropoxybenzaldehyde as a yellow oil. LC-MS (conditions A): tR=0.76 min.; [M+H]+: 165.24 g/mol.
