실험 절차

DOTA-G-tri-t-butyl ester 4, an intermediate compound in the synthesis of the conjugate 22, was synthesized starting with glycine benzylester hydrochloride (Aldrich), as described in Scheme 1. Chloroacetylchloride (Aldrich) was added to glycine benzylester hydrochloride in the presence of K2CO3 to produce N-(chloroacetyl)-glycine benzyl ester 1. The ester 1 was added to a suspension of DO3A-tri-t-butyl ester hydrochloride 2 (see U.S. Pat. No. 5,573,752) in K2CO3 to produce DOTA-G-tri-t-butyl-benzyl ester 3. Subsequent catalytic hydrogenation produced the DOTA-G-tri-t-butyl ester 4.
