Unfortunately, despite being of a very high purity, 32 similar, but different to 27, was also obtained as a wax; however, unlike 31 which was an orange wax, 32 was a pale-yellow wax. Last but not least, as envisaged, and in a manner similar to that for 26 (Scheme 6), the thus obtained InC 32 was successfully coupled to 28 via a stable N-acyl hydrazide linker, such that the crude product even survived flash column chromatography purification on silica to mark the first milestone towards synthesis of therapeutic NInC hybrids, and furnish the desired NInC 33 in acceptable yields (Scheme 8), and high purity, as evidenced by H NMR (ESI S53 †).
