Reaction Steps

1 g of NaNO2 is added to a solution of 3 g of the acid obtained in step A in 10 ml of water and 2 ml of 30% sodium hydroxide. This solution is poured over 1 hour into 10 ml of concentrated HCl cooled to 5° C. After stirring for 3 hours at 5° C., a solution of 7.5 g of SnCl2.2H2O in 15 ml of concentrated HCl is added slowly while the temperature is maintained at 5° C. The mixture is left stirring for one and a half hours at RT and filtered, and the residue is dried under vacuum to obtain 2.86 g of the expected product.
