Procedure

To a solution of 2-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)-5-(2,2-dimethyl-1,3-dioxolan-4-yl)-1,3-thiazole (470 mg) in tetrahydrofuran (3 mL) was added 1M hydrochloric acid (3 mL), and the mixture was stirred at room temperature for 3 days. The reaction mixture was diluted with ethyl acetate and washed with water. The ethyl acetate layer was washed with saturated aqueous sodium hydrogen carbonate and saturated brine, dried (MgSO4) and concentrated. The residue was subjected to preparative HPLC to give the title compound (280 mg, yield 64%) as a colorless amorphous solid. MS: 503 (MH+).
