Reaction Steps

Benzyl 2-(4-(4-(5-((5-(tert-butyl)oxazol-2-yl)amino)pyridin-2-yl)phenyl)-2-oxabicyclo[2.2.2]octan-1-yl)acetate (100 mg, 0.181 mmol) was dissolved in EtOAc/THF and hydrogenated with 10% Pd(OH)2/C under H2 balloon for 3 hr. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by prep-HPLC to give the title compound (28 mg, 31.5% yield). HR/MS [M+H]+: found 462.2390. calc. 462.2393. RT: 2.83 (Condition L). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.26 (s, 9H), 1.86-2.03 (m, 8H), 2.32 (s, 2H), 3.90 (s, 2H), 6.60 (s, 1H), 7.39 (d, J=8.59 Hz, 2H), 7.87 (d, J=8.59 Hz, 1H), 7.95 (d, J=8.59 Hz, 2H), 8.15 (dd, J=8.84, 2.78 Hz, 1H), 8.77 (d, J=2.78 Hz, 1H), 10.36 (br. s., 1H).
