実験手順
6 g (0.15 mol) of sodium hydroxide are added to a solution of 6.08 g (14 mmol) of methyl 4-[3-(1-adamantyl)-4-methoxyphenylureido]benzoate in 75 ml of methanol and the mixture is stirred at room temperature for 3 hours and then heated to re flux for 3.5 hours. The reaction mixture is evaporated, the residue is then taken up with 100 ml of water and the mixture is acidified to pH 1. The solid is filtered off, rinsed with water, dried and recrystallised in a tetrahydrofuran/hexane mixture to yield 2.78 g (87%) of 4-[3-(1-adamantyl)-4-methoxyphenylureido]benzoic acid, melting point 279°-282° C.
