Reaction Steps

Prepared using General Procedure 2. To a solution of (S)-5-(5-(1-((tert-butyldimethylsilyl)oxy)-2,3-dihydro-1H-inden-4-yl)thiazol-2-yl)-2-fluorobenzonitrile (116 mg, 0.25 mmol) in IPA (2 mL) was added sodium isopropoxide (21.1 mg, 0.25 mmol). The reaction mixture was heated at 60° C. for 2 h. Upon cooling, the solvent was evaporated and the product was purified by a silica gel column chromatography (EA/hexanes) to afford 151 mg (88%) of (S)-5-(5-(1-(tert-butyldimethylsilyloxy)-2,3-dihydro-1H-inden-4-yl)thiazol-2-yl)-2-isopropoxy-benzonitrile LCMS-ESI (m/z) calculated for C28H34N2O2SSi: 490.7, found 491.1 [M+H]+, tR=6.81 min (Method 1).
