Reaction Steps
To a stirred solution of 2-(5-chloro-pyridin-3-yloxy)-nicotinic acid (0.200 grams, 0.88 mmole), aminomethylcyclopropane hydrochloride (0.094 grams, 0.88 mmole), triethylamine (0.089 grams, 0.88 mmole) and 1-hydroxybenzotriazole hydrate (0.119 grams, 0.88 mmole) in dry dimethylformamide (3 ml) was added 1-(3-dimethylamino)-propyl)-3-ethylcarbodiimide hydrochloride (0.164 grams, 0.96 mmole) and stirred over night. The mixture was poured into 100 ml water and extracted with ethyl acetate. The combined organics were washed with 1 N NaOH, water and brine, dried over MgSO4, filtered and concentrated to give an oil that was purified by chromatography on silica gel eluting with 2.5% methanollmethylene chloride. Recrystalization from ethyl acetate/hexane gave a white solid (0.163 g). M.P. 105-107° C.; Anal. calcd. for C15H14N3O2Cl: C, 59.31;H, 4.65; N, 13.83. Found: C, 59.41;H, 4.68; N, 13.44.
