4-nitrophenylacetic acid. The acid chloride and ethyl malonate/butyl lithium afforded ethyl4-(4′-nitrophenyl)-3- oxobutanoate, of which the 3-oxo-function was converted to CF2 by sulphur tetrafluoride/hydrogen fluoride at room temperature. The nitro-group was reduced to amino, which was alkylated to bis(hydroxy- ethyl) amino using oxirane in acetic acid. Conversion to bis(chloro- ethyl) amino was by carbon tetrachl
