Procedure
A glass microwave reaction vessel was charged with 4-(5-(6-cyclopropylpyrazin-2-yl)-1H-indol-3-yl)-N-isopropyl-6-(4-methoxybenzyloxy)pyrimidin-2-amine (25 mg, 0.049 mmol) and TFA (1 mL, 12.98 mmol). The reaction was stirred and heated in a Initiator microwave reactor (Personal Chemistry, Biotage AB, Inc., Upssala, Sweden) at 120° C. for 20 min, then the solvent was removed and the residue was purified with RP-HPLC (10-50% ACN in water with 0.1% TFA) to give 6-(5-(6-cyclopropylpyrazin-2-yl)-1H-indol-3-yl)-2-(isopropylamino)pyrimidin-4(3H)-one (3.0 mg, 7.76 μmol, 15.73% yield) as a TFA salt. MS (ESI, pos. ion) m/z: 387.0 (M+1); 1H NMR (400 MHz, DMSO-d6) δ ppm 11.82 (1 H, br. s.), 8.82-9.07 (2 H, m), 8.48 (1 H, s), 8.14 (1 H, d, J=2.3 Hz), 7.88 (1 H, d, J=8.2 Hz), 7.56 (1 H, d, J=8.8 Hz), 6.10 (1 H, br. s.), 4.20-4.36 (1 H, m), 2.19-2.31 (1 H, m), 1.27 (6 H, d, J=6.5 Hz), 1.04-1.14 (4 H, m)
