Tetrahydrofuran → N-(4-decylphenyl)-2-hydroxy-[1,1'-biphenyl]-3-carboxamide

Participants

Reaction Steps

To a tetrahydrofuran (20 ml) solution of 4-decylaniline (3.07 g, 13.14 mmol), cooled to 0°-5° C. (inert atmosphere), is added n-butyllithium (2.3 M, 13.14 mmol). The deeply colored solution is stirred for ten minutes, after which a tetrahydrofuran (20 ml) solution of methyl 3-phenylsalicylate (1.00 g, 4.38 mmol) is added. The temperature is allowed to rise to 25° C. over a 30 minute period. The reaction is quenched by pouring the contents into 10% hydrochloric acid (100 ml). The organics are extracted into ethyl acetate, washed with 10% hydrochloric acid, dried (sodium sulfate), and concentrated to give 2.77 g of crude solid. Chromatography (Kieselgel 60, dichloromethane) affords N-(4-decylphenyl)-2-hydroxy-[1,1'-biphenyl]-3-carboxamide (1.69 g, 90%), mp 74°-75° C.
