Reaction Steps

A flask was charged with 5-(2-(1-(azetidin-3-yl)-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)naphthalene-2-sulfonamide (26.25 mg, 0.047 mmol), DCE (1 mL), AcOH (0.05 mL), and formaldehyde (37% aq.) (10.55 μl, 0.142 mmol). The mixture was stirred for 2 min, then sodium triacetoxyborohydride (20.03 mg, 0.094 mmol) was added in one portion. The resulting mixture was stirred for 3 h, then concentrated. The residue was dissolve in MeOH, and this solution was loaded onto a 500 mg SCX-2 ion exchange column (Biotage AB, Uppsala, SE). The column was eluted with methanol, then with 2N ammonia in methanol. The basic fraction was concentrated to afford 5-(2-(1-(1-methylazetidin-3-yl)-1H-pyrazol-5-yl)-4-(trifluoromethyl)phenyl)-N-(thiazol-2-yl)naphthalene-2-sulfonamide (23.53 mg, 0.041 mmol) as a beige-solid. 1H NMR (400 MHz, DMSO-d6) δ ppm=8.40 (s, 1H), 8.09 (d, J=7.9 Hz, 1H), 8.00 (d, J=6.9 Hz, 1H), 7.82 (s, 1H), 7.74 (d, J=8.4 Hz, 2H), 7.62-7.51 (m, 2H), 7.39 (d, J=6.8 Hz, 1H), 7.29 (s, 1H), 7.15 (d, J=4.1 Hz, 1H), 6.71 (d, J=4.0 Hz, 1H), 5.99 (s, 1H), 4.59 (td, J=7.3, 14.2 Hz, 1H), 3.66-3.59 (m, 1H), 3.33 (t, J=7.0 Hz, 1H), 3.09-2.95 (m, 2H), 2.27 (s, 3H). m/z (ESI) 570.2 (M+H)+.
