Reaction Conditions

Reaction Steps

K2CO3 (6.14 g, 44.4 mmol) and 2-iodopropane (1.28 mL, 12.76 mmol) were added successively to a stirred solution of 4-benzyloxy-2-hydroxybenzaldehyde (2.33 g, 10.21 mmol) in dry DMF (12.8 mL) at 25° C. under N2. The reaction was heated at 50° C. overnight. The reaction was diluted with water (50 mL) and extracted with Et2O (3×50 mL). The combined extracts were dried (MgSO4) and concentrated in vacuo to afford the crude product. This was azeotroped from toluene to afford 4-(benzyloxy)-2-isopropoxybenzaldehyde. LCMS calc.=293.1; found=292.9 (M+Na)+.
