Reaction Steps

A mixture of (S)—N-(3-(2-chloro-4-fluoro-5-(3-phenylureido)phenyl)-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-7-yl)pyrrolidine-2-carboxamide (43 mg, 0.078 mmol) in MeCN (3 mL) was treated with 0.1N HCl (aq.) (1.56 mL, 0.156 mmol), frozen and lyophilized. The material was treated with MTBE, sonicated, the solid collected via filtration and dried to afford (S)—N-(3-(2-chloro-4-fluoro-5-(3-phenylureido)phenyl)-1-ethyl-2-oxo-1,2-dihydro-1,6-naphthyridin-7-yl)pyrrolidine-2-carboxamide dihydrochloride (31 mg, 63% yield). MS (ESI) m/z: 549.2 [M+H]+.
