Sodium hydride → 4-(N-(2-Cyclohexylethyl)-N-p-toluenesulfonylaminomethyl)-2-(2-methylphenyl)benzoic acid, Methyl Ester

To a solution of N-2-cyclohexylethyl-p-toluenesulfonamide (300 mg) in DMF (5 mL) was added NaH (56 mg of a 60% dispersion in mineral oil). After gas evolution subsided, 4-bromomethyl-2-(2-methylphenyl)benzoic acid methyl ester (example 1178D, 266 mg) was added. After stirring at ambient temperature for 1.5 h, the reaction was quenched by addition of water (10 mL), and diluted with 50% EtOAc/hexane (50 mL). The organic solution was washed with water (10 mL), brine (2×10 mL), dried (MgSO4), filtered and concentrated. The residue was purified by silica gel chromatography eluting with 10% EtOAc/hexane to give the title compound as a colorless oil (250 mg, 70%).
