Prepared using General Procedure 3. To crude 5-(2-(1-(tert-butyldimethylsilyloxy)-2,3-dihydro-1H-inden-4-yl)thiazol-5-yl)-2-isopropoxybenzonitrile (0.043 g, 0.095 mmol) was added 4N HCl in dioxane (1.0 mL). The reaction mixture was stirred at room temperature for 2 h. The solvent was concentrated under a stream of N2 and the mixture dissolved in MeOH (1.0 mL). The crude product was purified by preparative HPLC to yield 0.02 g (43%) of 5-(2-(1-hydroxy-2,3-dihydro-1H-inden-4-yl)thiazol-5-yl)-2-isopropoxybenzonitrile 222. LCMS-ESI (m/z): calcd for: C22H20N2O2S: 376.5; found 377.1 [M+H] +, tR=3.31 min.
