반응 단계

To Mg (0.22 g, 9.05 mmol) under argon in Et2O (20 ml) was added dropwise a solution of bromide (4) (2.00 g, 8.23 mmol) in Et2O (20 ml). The mixture was refluxed for 2 h, a solution of cyclohexanone (1.00 ml, 9.87 mmol) in Et2O (5 ml) was added and the mixture was refluxed for 2 h. It was poured into iced water. The solution was extracted with ethyl acetate, dried over Na2SO4, filtered, and concentrated under vacuum to give 8.00 g as an oil. Triturating from diisopropyl ether afforded 2-(1-hydroxycyclohexyl)-6-methoxybenzothiophene as a white powder (0.90 g, 65%).
