Reaction Steps

tert-Butyl 3-((2-(methylthio)-5-(trifluoromethyl)pyrimidin-4-yl)ethynyl)benzoate (I18) (0.624 g, 1.58 mmol) and 10% Pd/C (0.206 g) was taken up in THF (20 mL) and H2 bubbled through the mixture for 5 minutes before stirring at room temperature for 20 hours under a hydrogen atmosphere. The mixture was filtered through celite and concentrated under reduced pressure. This procedure was repeated twice with 10% Pd/C (0.212 g) and 20% Pearlman's catalyst (0.316 g) respectively to give the title compound (I19) as a yellow oil that was reacted without further purification. LCMS Method C: rt 7.14 min.
