Procedure

2-(2-Hydroxyphenyl)-1,10-phenanthroline (4) (20 g, 73.45 mMole) was dissolved in tetrahydrofuran and with good stirring treated with lithium t-butoxide (5.65 g, 88.14 mMole). The precipitated product was stirred at room temperature in the reaction mixture for 1 hour to complete the reaction. The lithium 2-(1,10-phenanthrolin-2-yl)-phenolate was filtered off, washed well with diethyl ether and air-dried. Yield 21 g.
