Reaction Steps

To a solution of dimethoxynitrobenzene (30.0 g, 0.163 mol) in 99% methanesulfonic acid (300 ml) was added dl-methionine (31.8 g, 0.212 mol) and the mixture was stirred at rt for 24 h. The solution was poured onto ice and stirred with water (1.5 l). The precipitate was filtered and washed with water. The title compound was collected as a yellow solid (23.1 g, 84%).
