Methyl iodide → 3-[Methyl(methylsulfonyl)amino]-2-phenyl-N-[(1S)-1-phenylpropyl]quinolin-4-carboxamide

Participants

Reaction Steps

A solution of 3-[(methylsulfonyl)amino]-2-phenyl-N-[(1S)-1-phenylpropyl]quinolin-4-carboxamide (1) (459 mg, 1.0 mmol) in 5 ml DMF was added Cs2CO3 (325.8 mg, 1.0 mmol) and CH3I (62.3 μL, 1.0 mmol). The reaction mixture was stirred at RT under N2 for 2 h. All solvent was removed in vacuo and the residue was partitioned between ethyl acetate and 10% aqueous sodium bicarbonate solution, dried over sodium sulfate and then concentrated in vacuo. The residue was purified by recrystallization from ether/CH2Cl2 to give the title compound (210 mg, 44.4%) as a solid. 1H NMR (300 MHz, CDCl3) δ 0.94 (t, 3H), 1.97 (m, 2H), 2.71 (s, 3H), 3.43 (s, 3H), 5.10 (q, 1H), 5.14 (b, 1H), 7.32 (d, 2H), 7.34 (d, 2H), 7.39 (m, 1H), 7.78 (m, 2H), 7.84 (m, 2H), 8.08 (m, 1H), 8.30 (m, 2H), 8.42 (m, 2H). MS APCI, m/z=474 (M+1). LCMS: 2.32 min.
