Reaction Steps

A mixture of 2-(3-cyclopentyloxy-4-methoxyphenyl)-4-trifluoromethyl-imidazole (1.04 g, 3.18 mmol) and 5% aqueous ammonium hydroxide (300 ml) was heated to reflux for 24 hours. The reaction mixture was cooled and carefully neutralised with acetic acid. The mixture was extracted with methylene chloride (3×150 ml) and the volatiles removed in vacuo to afford the crude product. Flash chromatography (SiO2 ; EtOAc:hexane (2:3)) produced the 2-(3-cyclopentyloxy-4-methoxyphenyl)-4-cyanoimidazole (320 mg, 35%) as a pale yellow solid.
