Participants

Reaction Steps

The title compound was prepared by the method of Example 4(D) using N-(4-chloro-3-methyl-5-isoxazolyl)-N-(methoxyethoxymethyl)-2-[2-methyl-4,5-(methylenedioxy)benzyl]thieno[2,3-b]pyridine-3-sulfonamide (0.13 g, 0.23 mmoles), methanol (6 ml) and 4N HCl (2 ml). Recrystallization from chloroform/hexanes provided 70 mg (63%) of the title compound as a white crystalline solid, m.p. 182-184° C.
