The mixture was stirred for 1 h after which a solution of newly distilled 4-propyl-1-piperidone (0.96 g, 6.77 mmol) in dry tetrahydrofuran (20 ml) was added drop wise. The resulting mixture was stirred at-78 C for 30 min and then brought to ambient temperature. Water (100 ml) was added and the mixture was extracted with ethylacetate (3x100 ml). The combined organic phases was dried (MgS04), filtered and evaporated to dryness. The oily residue was purified by flash column chromatography (ethylacetate/methanol, 1: 1) to give the title compound (0.83 g).

To a solution of <strong>[2106-18-5]1-fluoro-2-(trifluoromethoxy)benzene</strong> [2106-18-5] (20.0 g, 111 mmol) in dry THF (200 mL), cooled to -78C, was added dropwise n-BuLi (2.5 M solution in n-hexane; 65 mL, 160 mmol) and subsequently TMEDA (60 mL). The reaction mixture was stirred for additional 60 min at -78C, followed by addition of a solution of iodine (30.2 g, 120 mmol) in dry THF (50 mL). The resulting mixture was stirred for 1 h and then quenched by addition of a saturated aqueous NH4CI solution (20 mL). The organic layer was washed with 1 N HCI, water and brine, and dried over MgS04. Volatiles were removed in vacuo to afford the title compound as yellow oil. The product was used in the next reaction step without further purification. MS (LC/MS): 306.0 [M+H]+.

Then MeCN (1.00 mL, 0.200 M) and a magnetic stir bar were added. The vial was capped and taken out of the glovebox. The reaction mixture was then stirred and irradiated with a 10 W LED (402 nm) at room temperature. After 16 h, an internal standard PhCF3 (5.84 mg, 4.95 pL, 0.04 mmol, 0.200 equiv) was added to the reaction vial, 0.200 mL of the resulting mixture was transferred to a 2 mL vial containing 0.500 mL of CDCI3. After the yield was determined using 19F NMR, the NMR sample was combined with the rest of the reaction mixture and the solvent was removed in vacuo. The crude material was purified by HPLC under noted conditions. The fractions containing the desired product were combined and extracted with CDCI3 (3 1 mL) , dried with magnesium sulfate, and filtered. The filtrate was concentrated in vacuo to furnish the desired product of trifluoromethoxylation . For volatile compounds, after purification by HPLC, the desired product was extracted with 1 mL CDC13 and then directly characterized.
