Reaction Steps
The title compound was prepared by the method of Example 4(B) using N-(4-chloro-3-methyl-5-isoxazolyl)-N-(methoxyethoxy-methyl)thieno[2,3-b]pyridine-3-sulfonamide (0.31 g, 0.75 mmoles)[Example 4(A)], THF (4 ml), t-BuLi (1.7 M, 0.53 ml, 0.90 mmoles) and 2-methyl-4,5-(methylenedioxy)benzaldehyde (0.15 g, 0.90 mmoles). Flash chromatography (40% EtOAc/hexanes) provided 0.16 g (38%) of the title compound.
