Reaction Steps
A stirred mixture of 6-methoxy-3-nitro-2-[(phenylsulfonyl)methyl]-pyridine (6.17 g, 20.0 mmol) in methanol and concentrated HCl (50 mL) is treated with thin strips of tin foil (10.0 g, 84.2 mmol), heated at 60° C. for 20 h, and filtered hot. The filtrate is poured over ice and 2.5N aqueous NaOH, stirred for 0.5 h and filtered. The filtercake is air-dried to afford the title compound as a white solid 5.26 g (94% yield), identified by mass spectral and HNMR analyses.
