Procedure

Lit., J. Org. Chem., 53:5695 (1988). To 14.3 g (328 mmol) sodium hydride (55% dispersion in oil) was added dropwise at 0° C. with stirring a solution of 10.1 g (88.5 mmol) (1RS,4RS)-cyclohex-2-ene-1,4-diol in 100 ml THF. 34 ml (546 mmol) methyl iodide was then added and stirring continued for an additional 48 h at room temperature. The reaction was quenched with saturated ammonium chloride solution and extracted with ether. The combined organic extracts were washed successively with saturated ammonium chloride solution and saturated brine, dried over sodium sulphate, and concentrated in vacuo to afford 11.5 g (91%) of the title compound as a yellow oil. 1H NMR d (250 MHz, CDCl3) 5.90 (2H, s), 3.82 (2H, br t), 3.37 (6H, s), 2.10 (2H, m), 1.51 (2H, m).
