A mixture of 4-(4-{3-[(1S)-1-(2-chloro-3-fluoro-6-methoxyphenyl)ethyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-5-methyl-1H-pyrazol-1-yl)cyclohexanone (12.0 mg, 0.0250 mmol), dimethylamine hydrochloride (20.34 mg, 0.2495 mmol), sodium triacetoxyborohydride (10.58 mg, 0.04990 mmol) and triethylamine (0.06 mL, 0.4 mmol) in 1,2-dichloroethane (3 mL, 40 mmol) was heated to 60° C. in a sealed tube for 1 h. The solution was extracted with DCM and sat. NaHCO3, and the organic layer was loaded onto silica gel for column chromatography, eluting with 3-7% (7N NH3 in MeOH)/DCM. The fractions containing the cis and trans products separately were concentrated in vacuo to afford the title compound as white solid. 1H NMR (400 MHz, CD3OD): δ=1.42-1.65 (m, 2H), 1.82 (d, J=7.1 Hz, 3H), 1.95-2.19 (m, 6H), 2.24 (s, 3H), 2.36-2.42 (m, 6H), 2.44-2.53 (m, 1H), 3.66 (br. s., 3H), 4.13-4.26 (m, 1H), 5.12 (q, J=7.1 Hz, 1H), 6.91 (dd, J=9.0, 4.2 Hz, 1H), 7.10 (t, J=9.0 Hz, 1H), 7.36 (d, J=1.3 Hz, 1H), 7.42 (s, 1H), 7.49 (s, 1H), 8.12 (d, J=2.0 Hz, 1H). MS (ES+): m/z=510.25/512.25 (100/50) [MH+]. HPLC: tR=1.18 min (polar—3 min, UPLC-ACQUITY).
