Reaction Steps

To a solution of methyl 4-hydroxybenzoate 23-1 (24.3 g, 160 mmol) in 250 mL of DMF was added 62 g (190 mmol) of Cs2CO3 followed by 20.4 mL (146 mmol) of cyclohexylmethyl bromide. The resulting slurry was then heated at 50° C. for 20 h. The solvent was distilled under reduced pressure and the residue was taken up in 500 mL of EtOAc. The organic phase was extracted with 1N NaOH (2×150 mL), water (5×150 mL) and brine (150 mL), dried (MgSO4) and concentrated to afford product 23-2 as a white solid.
