Sodium Hydroxide → HCID 54931697, compound

Participants

Reaction Steps

A solution of 3-nitrobenzylamine hydrochloride (1.0 g, 5.3 mmol) in DCM was converted to the free base by treating with 2 N NaOH. The organic layer was separated and concentrated, and the residue was redissolved in MeOH. To this solution was added methylvinylsulfone (232 μL, 2.6 mmol), and the reaction was stirred at rt. After 5 h, the crude reaction mixture was adsorbed onto silica gel and purified by column chromatography to generate the title compound in quantitative yield. 1H NMR (400 MHz, CDCl3) δ 8.21 (s, 1H), 8.13 (d, J=8.2 Hz, 1H), 7.67 (d, J=7.5 Hz, 1H), 7.51 (t, J=7.9 Hz, 1H), 3.93 (s, 2H), 3.16-3.24 (m, 4H), 3.01 (s, 3H). ES-LC/MS m/z=259 [M+H]+.
