Methyl 2-(3-chloro-4-hydroxyphenyl)acetate (177 mg, 0.885 mmol) was diluted with DMSO (3 mL) followed by the addition of K2CO3 (122 mg, 0.885 mmol) and N-(4-chlorophenethyl)-4-chloro-3-nitrobenzamide (300 mg, 0.885 mmol) (synthesized in step C). The reaction was heated to 85° C. and stirred for 12 hours. The reaction was cooled, diluted with DCM and washed with 10% aq. sodium carbonate, water and brine. The layers were separated and the organic layer was dried over H2SO4, filtered and concentrated. The material was purified using a biotage 40S cartridge eluting with DCM:MeOH (99:1) to yield methyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)-2-nitrophenoxy)-3-chlorophenyl)acetate (206 mg, 46.3% yield).
