The product from step (b) (10.3 g) was suspended in water (53 ml) and c.HCl (106 ml) added dropwise. The resulting mixture was cooled to -5° C. and a solution of sodium nitrite (3.2 g) in water (30 ml) added dropwise to the stirred mixture over 15 minutes followed by 30 minutes' stirring at -5° to 0° C. The solution was then added at 0° C. over 15 minutes to a stirred solution of tin (II) chloride (51 g) in c.HCl (91 ml), followed by 3 hours' stirring at room temperature.
