Reaction Steps
To a -30° C. solution of 2-hydroxy-2-methyl-1-(4-(methylthio)phenyl)propan-1-one (1.05 g, example 1, Step 2) in dichloromethane (20 mL) was added 3-phenylpropionyl chloride (1.68 g) in dichloromethane (10 mL) followed by pyridine (791 mg) and the mixture was allowed to warm up slowly to 25° C. and stirred for 12 h. Ethyl acetate was added to the mixture and it was washed with 1N HCl, brine, dried over magnesium sulfate filtered and the solvent was evaporated under vacuum. Purification by silica gel chromatography afforded 1.36 g of the title compound.
