4-Methyloxybenzyl chloride → HCID 15170715, 화합물

참여 물질

반응 단계

To a stirred solution of N-(2-mercapto-2-methylpropionyl)-L-cysteine (2.0 g) in ethanol(10 ml), 4N sodium hydroxide solution(7.7 ml) and paramethoxybenzyl chloride(3.0 ml) were added dropwise under ice-cooling and under nitrogen atomosphere. After the addition, the reaction mixture was stirred for 2 hours under ice-cooling and 2 hours at room temperature. The reaction mixture was concentrated in vacuo, acidified with 2N hydrochloric acid and extracted with ether. The organic layer was washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate and concentrated in vacuo to give crystals. The crystals were recrystallized with ether to give 2.8 g(67%) of the titled compound.
