实验过程
2-[2-tert-butoxy-1-(9H-purin-6-ylamino)ethyl]-3-phenyl-3H-quinazolin-4one was prepared using the general procedure described above with respect to compound 14, but 2-amino-6-chlorobenzoic acid was substituted for 2-amino-6-methylbenzoic acid in step A, 2-benzyloxycarbonylamino-3-tert-butoxy-propionic acid 2,5-dioxo-pyrrolidin-1-yl ester was substituted for 2-benzyloxycarbonylaminobutyric acid 2,5-dioxo-pyrrolidin-1-yl ester in step B, and the conditions used in step C removed both the benzyl protecting group and the A-Ring chloro substituent.
