4-(4-{4-[6-(4-methyl-piperazin-1-yl)-pyridin-3-yl]-thiazol-2-yl}-tetrahydro-pyran-4-yl)-benzoic acid (200 mg, 0.215 mmol), HATU (90 mg, 1.1 eq), H2N-OTBS (2.0 eq), and TEA (0.1 mL, 3 eq) were mixed in DMF and stirred for 2 hours. The reaction mixture was washed with water and then extracted with EtOAc. The organic phase was evaporated, suspended in 1N HCl, and slowly evaporated at 50° C. for 30 minutes to give title compound. MS found for C25H29N5O3S as (M+H)+ 480.15. 1H NMR (400 MHz, dmso-d6): δ: 11.13 (s, 1H), 8.99 (s, 1H), 8.68 (d, J=2.4 Hz, 1H), 8.00 (dd, J=8.8, 6.4 Hz, 1H), 7.81 (s, 1H), 7.68 (d, J=8.4 Hz, 2H), 7.50 (d, J=8.4 Hz, 2H), 6.87 (d, J=8.8 Hz, 1H), 3.73-3.70 (m, 2H), 3.61-3.56 (m, 2H), 3.53-3.50 (m, 4H), 2.65-2.60 (m, 2H), 2.44-2.20 (m, 4H), 2.38-2.32 (m, 2H), 2.22 (s, 3H).
