To a solution of 5-amino-6-((S)-2-imidazol-1-yl-1-phenyl-ethoxy)-3,4-dihydro-2H-naphthalen-1-one (100 mg, 0.288 mmol) in CH2Cl2 (2 mL) was added pyridine (47 mL, 0.576 mmol, 2 equiv) followed by benzenesulfonyl chloride (44 μL, 0.345 mmol, 1.2 equiv). The reaction was allowed to stir overnight at RT. The reaction was diluted with CH2Cl2, washed with saturated aqueous NH4Cl and brine, dried over MgSO4 to give an oil. Purification by chromatography (4% MeOH/CH2Cl2) gave the title compound as a white foam (114 mg, 0.234 mmol, 81%). The structure was confirmed by NMR and mass spectrometry. MS m/z 488 (M++H).
