Reaction Steps
Compound 68 was prepared using the general procedure described above with respect to compound 14, but 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 2-amino-6-bromopurine was substituted for 6-bromopurine in step D. The obtained 2-[1-(2-amino-9H-purin-6-ylamino)-2-tert-butoxy-ethyl]-5-methyl-3-phenyl-3H-quinazolin-4-one was then dissolved in trifluoroacetic acid and allowed to stir at ambient temperature for 5 hours. Purification by LC provided the product 68 as a white solid. MS (ES): m/z 429 (M+H), 215, 206, 151. Compound 68 is shown below.
