Product 1

HCID 866872191-{5-tert-Butyl-2-[2-(4-methyl-piperazin-1-yl)-ethyl]-2H-pyrazol-3-yl}-3-{(1S,4R)-4-[3-((S)-2-methyl-piperidin-1-yl)-[1,2,4]triazolo[4,3-a]pyridin-6-yloxy]-1,2,3,4-tetrahydro-naphthalen-1-yl}-urea formate saltYield 17%

Procedure

A yellow solution of Intermediate 127a (0.100 mmol) and N-methyl piperazine (0.056 mL, 0.50 mmol) in dry DMF (2 mL) was stirred at 75° C. for 2.5 h. The cooled solution was concentrated in vacuo, redissolved in MeOH (2 mL), applied to an SCX-2 cartridge (5 g) and washed with MeOH (20 mL). The product was eluted with 2M NH3 in MeOH (15 mL); concentration in vacuo left an orange solid. MDAP (Method 7) gave the title compound as an off-white solid (12 mg, 17%). LCMS (Method 5): Rt 3.36 min, m/z 669.5 [MH+]. 1H NMR (400 MHz, d6-DMSO): 0.91 (3H, d, J=6.3 Hz), 1.20 (9H, s), 1.49-1.56 (2H, m), 1.63-1.72 (2H, m), 1.75-1.85 (2H, m), 1.91-2.02 (2H, m), 2.04-2.10 (1H, m), 2.12 (3H, s), 2.14-2.21 (1H, m), 2.29 (4H, br s), 2.40 (4H, br s), 2.60 (2H, t, J=7.1 Hz), 2.91 (1H, ddd, J=12.2, 9.0, 4.0 Hz), 3.17 (1H, dt, J=12.0, 4.3 Hz), 3.28-3.36 (1H, m), 3.97 (2H, t, J=7.1 Hz), 4.87 (1H, td, J=8.5, 5.7 Hz), 5.54 (1H, t, J=4.3 Hz), 6.04 (1H, s), 6.95 (1H, d, J=8.6 Hz), 7.22 (1H, dd, J=9.8, 2.1 Hz), 7.29 (1H, td, J=7.2, 1.7 Hz), 7.34-7.41 (3H, m), 7.65 (1H, dd, J=9.8, 0.8 Hz), 7.71 (1H, d, J=2.1 Hz), 8.20 (1H, s), 8.27 (1H, s).
