3-(benzyloxy)-N-(1-methyl-1H-pyrazol-3-yl)-5-{(1S)-1-methyl-2-[(triisopropylsilyl)oxy]ethoxy}benzamide → 3-hydroxy-N-(1-methyl-1H-pyrazol-3-yl)-5-[((1S)-1-methyl-2-{[tris(1-methylethyl)silyl]oxy}ethyl)oxy]benzamide

Reaction Steps

10% Palladium on carbon was added to 3-(benzyloxy)-N-(1-methyl-1H-pyrazol-3-yl)-5-{(1S)-1-methyl-2-[(triisopropylsilyl)oxy]ethoxy}benzamide (21.7 g, 40.4 mmol) in dry THF (480 mL) under argon. The reaction mixture was degassed and placed under a hydrogen balloon and stirred for 16 hours. The atmosphere was replaced with argon and mixture was filtered through diatomaceous earth then the filtrate evaporated and dried under high vacuum for 1 hour to give the title compound (18.2 g).
