実験手順

1-(bromomethyl)-3-chloro-2-methoxybenzene. A mixture of 4-chloro-2-methoxy-1-methylbenzene (26.5 g, 169 mmol), NBS (33.1 g, 186 mmol) and benzoyl peroxide (200 mg, 0.826 mmol) in CHCl3 was heated to reflux for 24 h. The reaction was allowed to cool to RT and then concentrated in vacuo. The residue was stirred with petroleum ether and the resulting suspension was filtered off and the filtrate was concentrated in vacuo to give the title compound (30.9 g) as brown oil, which was used as it is in the next step. UPLC (2 min) rt 1.708 min.
