Reaction Steps
A reaction mixture of 2-{4-[6-amino-5-(4-fluoro-phenyl)-pyrimidin-4-yl]-piperazin-1-ylmethyl}-4,5-dichloro-phenol (80.0 mg; 0.18 mmol; 1.00 eq.), 3-iodo-azetidine-1-carboxylic acid tert-butyl ester (60.6 mg; 0.21 mmol; 1.20 eq.) and cesium carbonate (116.2 mg; 0.36 mmol; 2.00 eq.) in DMF (1 ml) was stirred at 90° C. overnight. The reaction solution was poured to water and extracted with ethyl acetate, The separated organic layer was washed with brine, dried and concentrated, which was then dissolved in methanol (1 ml) followed by adding 4.0 M HCl in dioxane (2 ml) and stirred at RT overnight. The reaction mixture was concentrated and purified by Waters prep-HPLC (acidic condition) to yield the title compounds (37 mg, yield 33.6%). LC-MS: (M+1=504, obsd.=504/506).
