Participants

Reaction Conditions

Reaction Steps

A mixture of 4-(3,4-dinitro-benzyl)-morpholine (1 mol. eq.) and 5% Pd/C (0.05 wt. eq.) in IMS (33 vol.) was stirred at 0-5° C. while the vessel was charged with hydrogen. The mixture was carefully warmed to 15-20° C. with stirring until the reaction was complete (<24 hours). The mixture was filtered and the filtrate evaporated to dryness to give 4-morpholin-4-ylmethyl-benzene-1,2-diamine (90%). The material was used immediately in the next step. (LC/MS (basic method): Rt 1.64, [M—N(CH2CH2)2O—]+ 121).
