Trifluoroacetic acid → 1-(5-tert-Butyl-2-p-tolyl-2H-pyrazol-3-yl)-3-[(1S,4R)-4-(3-piperidin-4-ylmethyl-[1,2,4]triazolo[4,3-a]pyridin-6-yloxy)-1,2,3,4-tetrahydro-naphthalen-1-yl]-urea

Reaction Steps

An orange solution of Intermediate 22c (155 mg, 0.211 mmol) and TFA (0.157 mL, 2.11 mmol) in DCM (3 mL) was stirred at RT for 3 h. The solution was concentrated in vacuo, redissolved in MeOH (1 mL), applied to an SCX-2 cartridge (2 g) and washed with MeOH (15 mL). The product was eluted with 2M NH3 in MeOH (15 mL); concentration in vacuo left the title compound as a pale brown solid (116 mg, 87%). LCMS (Method 3): Rt 2.90 min, m/z 633 [MH+].
