Methyl iodide → HCID 118271795, compound

Participants

Reaction Steps

At 0° C., to a suspension of NaH (0.13 g, 2.96 mmol) in anhydrous THF (5 mL), was added a solution of (S)-1-(bis(4-methoxybenzyl)amino)-2-methyl-1-phenylpropan-2-ol 4 (1.0 g, 2.47 mmol) in anhydrous THF (10 mL). After 15 min, MeI (0.55 g, 3.71 mmol) was added and the contents were heated to reflux. After 8 h, the reaction was brought back to ambient temperature, quenched carefully with ice cold H2O (10 mL), and the organic contents were extracted with EtOAc (3×25 mL). The combined organic extracts were washed with brine (1×20 mL), dried over Na2SO4, concentrated to afford (S)-2-methoxy-N,N-bis(4-methoxybenzyl)-2-methyl-1-phenylpropan-1-amine. H1NMR (CD3OD, 400 MHz) δ 7.45-7.44 (m, 2H), 7.37-7.34 (m, 2H), 7.33-7.28 (m, 5H), 6.88-6.86 (m, 4H), 4.20 (s, 1H), 3.78 (s, 6H), 3.25 (s, 4H), 2.81 (s, 3H), 1.4 (s, 3H), 0.81 (s, 3H). MS: [M+H]+ m/z 420.
