The product of step B (100 mg, 0.201 mmol) was diluted with 7N ammonia/methanol (10 mL), followed by addition of ethyl acetate (10 mL). Once the material dissolved, Raney Nickel (1.72 mg, 0.0201 mmol) was added and the reaction was purged three times with a balloon of hydrogen. After stirring for 12 hours, the reaction mixture was filtered through a GF/F filter and concentrated. The residue was purified using a biotage 12i column eluting with methylene chloride:MeOH:NH4OH (90:9:1) to yield tert-butyl 2-(3-(aminomethyl)-4-(4-(3,4-dichlorobenzamido)phenoxy)phenyl)acetate (100 mg, 99.2% yield) as a clear oil.
