실험 절차

wherein X1, X2, Z, and R1 are as defined above. The pyrrole can reacted with t-butylchloride under Friedel-Craft alkylation condition to give the tert-butylpyrrole 2, which can then be nitrated. The ester is then hydrolyzed, e.g., with LiOH, and coupled to give amide 4. Compound 4 is then reduced to give the amine which is reacted with isocyanate to give compound 5, which is an exemplary compound of Formula I.
