Hydroxylamine HCl → (2-(2-Amino-3-morpholinoquinolin-6-yl)-3-methylphenyl)(phenyl)methanone oxime

Participants

Reaction Steps

To a solution of (2-(2-amino-3-morpholinoquinolin-6-yl)-3-methylphenyl)(phenyl)methanone (0.090 g, 0.213 mmol, prepared as Example 15, Step 1) in MeOH (4.0 mL) was added hydroxyammonium chloride (0.044 mL, 1.063 mmol) followed by 3 drops of pyridine. The reaction mixture was brought up to reflux for 41 h until the conversion was completed, determined by LCMS. The reaction mixture was cooled to RT and purified on HPLC (10-100% MeCN/H2O with 0.1% TFA) to afford (2-(2-amino-3-morpholinoquinolin-6-yl)-3-methylphenyl)(phenyl)methanone oxime as a off-white solid. MS (ESI, pos. ion) m/z: 439 (M+1).
