反応手順
A procedure analogous to the preparation of Example 5 was followed. The appropriate succinate ester was prepared using the method disclosed in PCT publication WO 98/51665, using 2-(cyclopentyl)ethyl iodide for R3—X in place of allyl bromide (see Scheme 2). The anti-succinate half-ester was coupled to (S)-isomer benzodiazepine (30) using the procedures of Step 1. After Steps 2 and 3, the title compound was isolated. MS (M+H)+=475; (M+Na)+=497.2.
