YieldReaction ConditionsOperation in experiment
In ethanol; at 20℃; for 5h; To a solution of the title compound from above step A (1.5 g, 6.7 mmol) in ethanol (100 mL) was added ketone derivative (1.6 g, 6.7 mmol) in ethanol (50 mL). The reaction mixture was stirred for 5 h at room temperature. The solvent was removed to give the title compound as a solid (3.1, quantitative). The product was used in the next step without any purification.

YieldReaction ConditionsOperation in experiment
82% In ethanol; for 0.5h;Reflux; General procedure: To a solution of 5-bromo-2-hydrazinopyridine (1; 0.56 g, 3.0 mmol) in EtOH (5 mL) was added a solution of the corresponding carbonyl compound (3.0 mmol) in EtOH (5 mL) in one portion. The reaction mixture was refluxed for 30 min, evaporated under vacuum to a constant mass to give the corresponding hydrazone 5 (solid hydrazones 5c,d,f,k,o?r were recrystallized from appropriate solvent, isolated, and characterized by spectroscopical and physical data). Freshly prepared21 polyphosphoric acid (5.0 g) was added to the residue, the mixture was heated with stirring to 160 °C and maintained for 5 min at 160?180 °C. After cooling to 20?30 °C, the reaction mixture was treated with H2O (25?30 mL). The obtained solution (or suspension) was cooled to 0 °C and adjusted to basic pH with 25percent aq ammonia.The precipitate that formed was collected by filtration, washed with ice water (10 mL), H2O?MeOH mixture (1:5, 1 mL), and air-dried. In case, if the product separated as an oil, the reaction mixture was extracted with CH2Cl2 (3 × 20 mL), the combined extracts were dried (Na2SO4), and evaporated to dryness. The obtained precipitate was recrystallized from appropriate solvent or washed with H2O?MeOH mixture (1:5, 1 mL) (Table 1).
