Reaction Steps
The title compound was prepared by the method of Example 5(A) using N-(4-chloro-3-methyl-5-isoxazolyl)-N-(methoxyethoxymethyl)-2-(α-hydroxy-2,6-dimethoxybenzyl)thieno[2,3-b]pyridine-3-sulfonamide (0.13 g, 0.22 mmoles), CH2Cl2 (5 ml), triethylsilane (0.35 ml, 2.2 mmoles) and boron trifluoride etherate (0.16 ml, 1.3 mmoles). Flash chromatography (40% EtOAc/hexanes) provided 0.11 g (85%) of the title compound as a colorless oil.
