Reaction Steps

To a solution of methyl 4-aminophenylacetate (5.5 g, 33.3 mmol) in concentrated HCl (35 mL) at 0° C. is added a solution of NaNO2 (2.3 g, 33.3 mmol) in water (10 mL). The temperature of the reaction is maintained at 0-5° C. After stirring for 30 minutes, a solution of SnCl2 (19 g, 99.9 mmol) in concentrated HCl (10 mL) is added and the mixture is vigorously stirred with a stirring rod. The mixture is then diluted with water (50 mL), and the resulting precipitate is collected by suction filtration and washed with water. The solid is dried under vacuum to give 5 g of 18, which is used without further purification.
