Reaction Steps

To a solution of 4-[4-(6-chloro-3-pyridyl)imidazolyl]butylamine (825 mg, 3.3 mmoles) in ethanol (15 ml) was added sodium ethoxide (2.24 g, 33 mmoles). The reaction mixture was heated in a sealed vessel in a 130° C. oil bath for 48 hours; upon cooling more sodium ethoxide was added (1.0 g) and the closed vessel was heated at 150° C. for 48 hours more. Upon cooling the reaction mixture was concentrated and than was taken up in dichloromethane (200 ml) and was washed with water (50 ml). The aqueous layer was extracted further with dichloromethane (2×200 ml), the combined organics were dried over MgSO4, filtered, and concentrated yielding 4-[4-(6-ethoxy-3-pyridyl)imidazolyl]butylamine (747 mg, 87%).
