Trityl chloride → Triethylammonium 2-triphenylmethoxyimino-2-(fur-2-yl) acetate

Participants

Reaction Steps

Triethylamine (35 ml, 250 mmole), triphenylchloromethane (35 g, 125 mmole) and 2-hydroxyimino-2-(fur-2-yl)-acetic acid (syn isomer) 15.505 g, 100 mmole) were reacted together essentially as described in Preparation 2(a) to give triethylammonium 2-triphenylmethoxyimino-2-(fur-2-yl) acetate (syn isomer) as a pale-yellow solid (39.5 g, 79 mmole, 79%), m.p. 170° to 172° (dec), λmax 275.5 nm, inflexions at 265 and 271.5 nm (ε 17,900; 15,900 and 17,500 respectively). (b) The title compound was prepared from the product of (a) above essentially as described in Preparation 2(b) and used without further purification in Example 2.
