Reaction Steps

A mixture of 4-(benzyloxy)phenol (2.01 g, 10.1 mmol), K2CO3 (1.60 g, 11.6 mmol) and 3-chloro-2-methylpropene (93) (2.00 mL, 20.4 mmol) in anhydrous acetone (2.5 mL) was stirred in a sealed vial at 58° C. for 24 h. The resulting mixture was filtered, washing with CH2Cl2, and then the filtrate was evaporated to dryness and the residue was chromatographed on silica gel. Elution with petroleum ether firstly gave foreruns, and then further elution with 25% CH2Cl2/petroleum ether gave 1-(benzyloxy)-4-[(2-methyl-2-propenyl)oxy]benzene (94) (Karrer, F. DE 2312518) (1.74 g, 68%) as a white solid: mp (CH2Cl2/hexane) 62-64° C.; 1H NMR (CDCl3) δ 7.45-7.29 (m, 5H), 6.90 (dt, J=9.3, 2.8 Hz, 2H), 6.85 (dt, J=9.3, 2.8 Hz, 2H), 5.08 (m, 1H), 5.01 (s, 2H), 4.79 (m, 1H), 4.38 (s, 2H), 1.82 (s, 3H).
