10H-Phenothiazine-2-carboxylic acid → HCID 11342902, compound

Participants

Reaction Steps

The experimental protocol of this peptide condensation is the same as that described for the synthesis of intermediate 1.1, this time using 10H-phenothiazine-2-carboxylic acid (intermediate 1.10) and L-leucyl-L-leucyl-N1-[(3S)-2-methoxytetrahydrofuran-3-yl]-L-leucinamide (intermediate 1.8). The reaction product is purified by chromatography on silica (eluent: ethyl acetate/heptane in proportions of 7/3 to 1/1). 228 mg of a yellow solid is obtained with a yield of 21%. Melting point: 164-165° C.
