Versuchsvorschrift
The product of Step 1 (150 mg, 0.362 mmol) was dissolved in THF (2 mL), to which was added 100 mg of LAH (2.63 mmol) at 0° C. The reaction was stirred at 0° C. for 10 min and was quenched by Fischer work up: careful successive dropwise addition of 0.1 mL of water, 0.1 mL of 15% NaOH solution, and 0.3 mL of water provided a granular inorganic precipitate that was easy to rinse and filter. The granular precipitate was filtered and washed with EtOAc. The combined organic solution was concentrated to give the crude product that was purified by column (95-100% EtOAc in hexanes) to afford the title compound. 1H NMR (500 MHz, (CDCl3): 8.39 (s, 1H), 8.05 (s, 1H), 7.86 (d, 2H), 7.48 (d, 1H), 7.06 (d, 2H), 6.81 (d, 1H), 3.67 (s, 3H), 3.61 (d, 2H), 3.02 (broad s, 1H), 1.83 (m, 1H), 1.45 (m, 1H), 0.97 (m, 2H). LCMS: m/z 372 (M+H)+. Human FAAH lysate assay: IC50=88.4 nM.
