Reaction Steps

The N-((3R)-1-{[(4R)-2,2-dimethyl-1,3-dioxolan-4-yl]methyl}piperidin-3-yl)-4-[6-(3-methoxyphenyl)imidazo[2,1-b][1,3]thiazol-5-yl]pyrimidin-2-amine (150 mg, 0.288 mmol) was dissolved in MeOH (10 ml) and water (1.2 ml) and treated with trifluoroacetic acid (90 uL). The mixture was stirred at 50° C. overnight (18 hours). The mixture was neutralized with potassium carbonate (160 mg) and the volatiles were removed in vacuo. The product was purified by flash chromatography (6:1 EtOAc/MeOH), affording the title compound as an off-white solid (120 mg, 87%). M.p.=106-108° C. 400 MHz 1H NMR (DMSO-d6) δ: 8.72 (br. s, 1H), 8.08 (d, J=5.5 Hz, 1H), 7.44 (d, J=4.4 Hz, 1H), 7.36 (t, J=7.9 Hz, 1H), 7.16-7.10 (m, 2H), 7.06-6.97 (m, 2H), 6.36 (d, J=5.5 Hz, 1H), 4.40-4.15 (m, 1H), 4.02-3.90 (m, 1H), 3.77 (s, 3H), 3.68-3.56 (m, 2H), 3.40-3.28 (m, 2H), 3.05-2.95 (m, 1H), 2.80-2.64 (m, 1H), 2.42 (br. s, 1H), 2.32 (br. s, 1H), 2.14 (br. s, 1H), 1.90-1.80 (m, 1H), 1.75-1.65 (m, 1H), 1.60-1.45 (m, 1H), 1.45-1.30 (m, 1H). LCMS: 481 [M+H].
