Reaction Steps

Methanesulfonyl chloride (0.45 g, 3.88 mmol) was added dropwise to a solution of 3-(2,4,5-trifluorophenyl)propan-1-ol (0.46 g, 2.41 mmol; from Step 2) and triethylamine (0.71 g, 7.0 mmol) in dichloromethane (5 mL) at 0° C. The mixture was stirred at room temperature for 2 h. After complete disappearance of the alcohol (HPLC monitoring), dichloromethane (10 mL) and water (10 mL) were added. The aqueous phase was saturated with NaCl and extraction performed. The organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo to give 0.66 g (100%) of the title compound as a yellow oil. Purity by HPLC: 87%. This material was used directly in the next step.
