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.
