Reaction Steps

2-((2-amino-4-bromophenyl)(methyl)amino)ethanol (3.09 g, 0.013 mol) was dissolved in DCM (100 mL) with DMF (10 drop), Thionyl chloride (1.8 g, 0.015 mol in 10 ml DCM) was added dropwise at 0° C. The reaction was stirred at rt for 10 min then 80° C. for 30 min, rt for 16 h. The mixture was partitioned between 1N NaOH and DCM (2×30 ml). The combined organic layers was concentrated to give 3.2 g, (96.3%) of 4-bromo-N1-(2-chloroethyl)-N1-methylbenzene-1,2-diamine LCMS-ESI+ (m/z): [M+H]+ calcd for C9H12BrClN2:261.99; found 262.9.
