실험 절차: To a solution of 1-methyl-1-hydroxycarbonylcyclohexane (10 g, 70 mmol) in tetrahydrofuran (300 mL) at 0° C. was added 1 M diborane in tetrahydrofuran (200 mL, 200 mmol) over 90 minutes. The cooling bath was removed and the reaction mixture was stirred at room temperature for two days. The remaining borane was quenched by the slow addition of saturated sodium bisulfate (10 mL) over 90 min with cooling. Additional saturated sodium bisulfate (200 mL) was added and after 20 min of stirring the aqueous layer was removed. The organic layer washed with water and saturated sodium chloride, dried, filtered and concentrated. The residue was purified by flash chromatography using 20% diethylether in hexanes to give 1-methyl-1-hydroxymethylcyclohexane (6.17 g, 48 mmol, 69%).

실험 절차: Under ice cooling and stirring, hydrogen chloride was blown into a mixture of 128 g of (1-methylcyclohexyl)methanol, 400 g of hexane, and 36 g of paraformaldehyde, until the is reactant alcohol disappeared on gas chromatography analysis. The excess hydrogen chloride was purged by feeding nitrogen into the reactor, after which the water layer was removed by separatory operation. The solution was dried over magnesium sulfate and the solids filtered off, yielding a hexane solution of chloromethyl[(1-methylcyclohexyl)methyl] ether.
