Reaction Steps

2,3-Dihydro-5-nitro-7-(pyrid-3-yl)benzofuran (D63) (0.19 g, 0.00079 mole) in ethanol (20 ml) was treated with a solution of tin II chloride (0.75 g, 0.0040 mole) in conc. hydrochloric acid (1 ml) and heated at 50° C. for 2 hours. A further 0.38 g tin II chloride in conc. hydrochloric acid (0.5 ml) was added and the mixture was heated at 50° C. for ½ hour and stirred at ambient temperature for 18 hours. Deionised water (5 ml) was added and the mixture was basified with 10% sodium hydroxide solution, extracted into ethyl acetate, dried (Na2SO4) and evaporated in vacuo to afford the title compound (0.13 g, 82%) as a dark oil.
