Reaction Steps

A similar procedure (Iyer, R. P. et al. Synth. Commun. 1995, 25, 2739-2749) to that described for the preparation of 41 was followed using p-anisoyl chloride (5.0 g, 29.4 mmol), paraformaldehyde (883 mg, 29.4 mmol) and zinc chloride (31 mg, 0.22 mmol), at 80° C. for 16 h. Purification by flash chromatography (hexane/ethyl acetate 4:1) afforded chloromethyl p-methoxybenzoate (48) as a yellow oil (0.74 g, 3.69 mmol, 12%). 1H NMR (300 MHz, CDCl3) δ 3.87 (3H, s, OMe), 5.94 (2H, s, CH2), 6.92-6.96 (2H, m, Ar), 8.01-8.06 (2H, m, Ar).
