2,3-Dimethylbenzaldehyde → N-(2,3-Dimethylbenzyl)cyclopropanamine

関与物質

反応手順

A mixture of 2,3-dimethylbenzaldehyde (1 eq.), cyclopropylamine (1.2 eq.) and sodium bicarbonate (1.5 eq.) were heated at reflux in MeOH (0.5 M) for 1 h. The reaction mixture was then cooled in ice and sodium borohydride (1.2 eq.) was introduced portionwise. Following the completion of addition, the reaction mixture was warmed to RT and stirred at RT for 1 h. The volatiles were then removed in vacuo and the resulting residue was partitioned between H2O and CH2Cl2. The organic layer was separated, washed with brine, dried over MgSO4 and filtered. Concentration of the filtrate in vacuo afforded the title compound as a light yellow oil.
