To a mixture of N-[(1R)-1-(5-bromopyridin-2-yl)ethyl]-2-(4-isopropylphenyl)-acetamide (40 mg, 0.11 mmol), tetrakis(triphenyl)phosphine)palladium (0) (1.3 mg, 0.01 mmol), sodium carbonate (22 mg, 0.20 mmol) in DME/water (4:1, 3.0 ml) was added 3-pyridyl boronic acid (19 mg, 0.16 mmol). The reaction was heated for ten minutes in the Smith Personal microwave system at 100° C. and then washed with brine. Organics were extracted with EtOAc and dried over Na2SO4, filtered and concentrated in vacuo to give a red oily solid. Reverse phase prep HPLC chromatography afforded the mono-trifluoroacetate salt of N-[(1R)-1-(3,3′-bipyridin-6-yl)ethyl]-2-(4-isopropylphenyl)acetamide as an oil. 1H NMR (CD3OD, 400 MHz) δ 9.18 (s, 1H); 8.95 (s, 1H); 8.84 (d, J=4.80 Hz, 1H); 8.78 (dd, J=1.20 Hz and 6.40 Hz, 1H); 8.29 (dd, J=2.40 and 8.40 Hz, 1H); 8.06 (dd, J=5.20 and 8.20 Hz, 1H); 7.61 (d, J=8.40 Hz, 1H); 7.19 (m, 4H); 5.10 (q, J=6.80 Hz, 1H); 3.55 (s, 2H); 2.86 (m, 1H); 1.55 (d, J=7.20 Hz, 3H); 1.21 (d, J=6.80 Hz, 6H); HRMS (ES) exact mass calcd for C23, H25, N3O: 360.2071, Found: 360.2070
