[1-(2-methylpropyl)cyclohexyl]methanol

Condiciones: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedimiento: To a solution of lithium diisopropylamide (2.0 M, 7.74 mL) at −78° C. was added methyl cyclohexanecarboxylate (2.0 g) dropwise as a solution in tetrahydrofuran (20 mL). After stirring for 30 minutes. 1-iodo-2-methylpropane (1.956 mL) was added dropwise as a solution in tetrahydrofuran (1 mL). The reaction was allowed to warm to room temperature and stirred overnight. The reaction was quenched with 1N HCl (25 mL) and diluted with water (25 mL) and extracted into diethyl ether (50 mL). The ether layer was washed with brine (30 mL), dried over magnesium sulfate, filtered and concentrated. The residue was dissolved in diethyl ether (25 mL) and lithium aluminum hydride (1.0M in tetrahydrofuran, 16.88 mL) was added dropwise. After stirring overnight, the reaction was quenched with water (0.65 mL), 15% aqueous NaOH (0.65 mL), more water (1.95 mL), then magnesium sulfate was added and the reaction filtered and concentrated. The residue was loaded onto silica gel and eluted using a gradient of 3% to 20% ethyl acetate/hexanes to provide the title compound. stirred overnight The reaction was quenched with 1N HCl (25 mL) diluted with water (25 mL) extracted into diethyl ether (50 mL) The ether layer was washed with brine (30 mL) dried over magnesium sulfate filtered concentrated The residue was dissolved in diethyl ether (25 mL) lithium aluminum hydride (1.0M in tetrahydrofuran, 16.88 mL) was added dropwise After stirring overnight the reaction was quenched with water (0.65 mL), 15% aqueous NaOH (0.65 mL), more water (1.95 mL) magnesium sulfate was added the reaction filtered concentrated eluted
