Procedure

A stirred mixture of 6-((6-bromo-3H-imidazo[4,5-b]pyridin-3-yl)methyl)-2-(methylsulfinyl)benzo[d]thiazole from Example 29 (210 mg, 0.3 mmol), (1R,2R)-1-amino-2,3-dihydro-1H-inden-2-ol (92 mg, 0.6 mmol), and DIEA (267 μL, 1.5 mmol) in DMA (3 mL) was heated at 130° C. for 120 h in a sealed tube. The mixture was cooled to rt and subjected to purification by reverse-phase preparative HPLC using a mixture of water (5% CH3CN, 0.05% HCOOH) and CH3CN (0.05% HCOOH) as the mobile phase and Varian Pursuit XRs C18 column as the stationary phase to afford (1R,2R)-1-((6-((6-bromo-3H-imidazo[4,5-b]pyridin-3-yl)methyl)benzo[d]thiazol-2-yl)amino)-2,3-dihydro-1H-inden-2-ol (5.4 mg, 4%) as a white powder. 1H NMR (300 MHz, DMSO-d6) δ 8.68 (s, 1H), 8.36-8.54 (m, 3H), 7.71 (s, 1H), 7.35 (m, 1H), 7.11-7.30 (m, 5H), 5.51 (s, 2H), 5.18 (t, J=7.0 Hz, 1H), 4.30 (m, 1H), 3.16 (dd, J=7.2, 15.8 Hz, 1H), 2.74 (dd, J=7.3, 15.4 Hz, 1H). LCMS (ESI) m/z 492 and 494 (M+H)+.
