반응 단계
1-{2-[(4-Bromophenyl)sulfonyl]benzyl}-3-fluoropiperidine (prepared according to the methods of Example 75 Step 1 followed by Example 74 using 3-fluoropiperidine; 63 mg, 0.152 mmol), 2-fluorostyrene (36 μL, 0.3 mmol), sodium acetate (25 mg, 0.3 mmol) and palladium(I) chloride (1 mg) were combined in 1-methyl-2-pyrrolidinone (0.5 mL) and heated for 2 hours at 130° C. The cooled reaction mixture was partitioned between ethyl acetate and brine. The organic layer was washed further with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by column chromatography on silica, eluting with 30% ethyl acetate/isohexane, to give the title compound. δH (400 MHz, d6 DMSO): 8.19 (1H, d, J=6.3 Hz), 8.00-7.97 (2H, m), 7.86-7.82 (2H, m), 7.77 (4H, s), 7.48-7.34 (3H, m), 7.23-7.19 (2H, m), 5.15 (1H, d, J=49 Hz), 4.72 (1H, d, J=13.4 Hz), 4.45-4.40 (1H, m), 3.79-3.73 (1H, m), 3.55-3.51 (1H, m), 3.45-3.32 (2H, m), 3.20-3.14 (1H, m), 1.99-1.93 (2H, m), 1.73 (1H, d, J=12.1 Hz). m/z (ES+) 454 [MH+].
