Reaction Steps

To a solution of quinolin-6-ylamine (5 g, 35 mmol) in cone. HCl (12 mL) was added dropwise an aqueous solution (4 mL) of NaNO2 (2.42 g, 35 mmol) at 0° C. The resulting mixture was stirred for 1 h and then treated dropwise with a solution of SnCl2.2H2O (15.8 g, 70 mmol) in cone. HCl (15 mL) at 0° C. The reaction mixture was stirred for 2 h at RT. The precipitate was collected and washed with EtOH and Et2O to yield 1-(quinolin-6-yl)hydrazine hydrochloride (4.3 g, 77% yield) as a yellow powder, which was used for the next reaction without further purification.
