YieldReaction ConditionsOperation in experiment
97% With hydrazine hydrate; In ethanol;Reflux; General procedure: To 2-chloropyridine (1.1 mmol) in ethanol (5.0 mL) was added hydrazine hydrate (2 mL) dropwise at room temperature. The mixture was refluxed until completion as monitored by TLC. The reaction mixture was cooled, ethanol was removed by evaporation. Then, the residue was partitioned between ethyl acetate and water. The combined organic phase was dried over anhydrous sodium sulfate and concentrated to give the product, which was used for the following cyclization reaction without purification.

YieldReaction ConditionsOperation in experiment
23% 631 mg (3.0 mmol) of the compound from Example 3A and 531 mg (3.0 mmol) of the compound from Example 25A are initially introduced into 10 ml ethanol. 114 mg (0.6 mmol) p-toluenesulfonic acid monohydrate are added and the mixture is stirred under reflux for 16 h. It is then concentrated and the residue is purified by means of preparative HPLC (RP18 column; mobile phase: acetonitrile/water gradient with addition of 0.1% TFA). The product fractions are combined, the solvent is removed and the residue is dried under a high vacuum. 20 ml of a 4 N solution of hydrogen chloride in dioxane are added and the mixture is stirred at RT for 1 h. The solid is filtered off, washed twice with tert-butyl methyl ether and dried under a high vacuum.Yield: 231 mg (23% of th.)LC-MS (Method 8): Rt=1.65 min; MS (ESIpos): m/z=297 [M+H]+;1H-NMR (400 MHz, DMSO-d6): delta=8.81 (d, 1H), 8.70 (s, 1H), 8.59 (s, 1H), 8.47 (s, 1H), 7.92 (s, 1H), 7.77 (d, 1H).

YieldReaction ConditionsOperation in experiment
79% With Imidazole hydrochloride; at 153℃; General procedure: A mixture of 2-hydrazinylpyridine (0.5 mmol), imidazolium chloride (0.05 mmol) in DMF (2.0 mL) was stirred at 153 for 3-16 hours. The reaction was monitored by TLC. Upon completion, DMF was removed by rotary evaporator and the residue was applied for purification by flash column chromatography on silica gel to afford the desired product.
