Reaction Steps

A solution of tert-butyl 4-{(1-hydroxycyclohexyl)[4-hydroxy-3-(trifluoromethoxy)phenyl]acetyl}piperazine-1-carboxylate (0.35 g 0.72 mmol) (See Example 400, step 1) and iodomethane (0.16 g, 1.08 mmol) in N,N′-dimethylformamide (5 mL) was treated with potassium carbonate (0.12 g, 0.86 mmol), and the solution was stirred at room temperature for 16 hours. The reaction was then poured into water and extracted 3 times with ethyl acetate. The combined extracts were washed twice with water, then dried over magnesium sulfate and concentrated to afford 0.31 g of tert-butyl 4-{(1-hydroxycyclohexyl)-[4-methoxy-3-(trifluoromethoxy)phenyl]acetyl}piperazine-1-carboxylate). The product was used in the next step without further purification.
