Reaction Steps

In analogy to the procedure described in example 9.1, 3-amino-4-methyl-benzoic acid methyl ester ([18595-18-1]) was reacted with triphosgene in the presence of Et3N in CH2Cl2 under reflux conditions for 16 h to give the title compound as brown solid which was used in the next step without further purification. MS: m/e=191 [M+].
