Reaction Steps
4-[4-(6-chloro-3-pyridyl)imidazolyl]butylamine. To a solution of 2-[4-(4-chloro-pyridin-3-yl)-imidazol-1-ylmethyl]-isoindole-1,3-dione (2.82 g, 7.42 mmoles) in ethanol (75 ml) was added hydrazine (0.58 ml, 18.6 mmoles). After heating the reaction mixture in a 65° C. oil bath for 15 hours, the solution was cooled, filtered, and concentrated. The resulting oil was taken up in dichloromethane (200 ml) and was washed with 1M NaOH (250 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-(4-chloro-3-pyridyl)imidazolyl]butylamine (1.74 g, 94%).
