General procedure: 1.2.2.1. General method Bl To a stirred solution of Intermediate Gen-1 (1 to 1.2 eq.), and amine derivative (1 eq.) in DCM or DMF are added TBTU or HATU (1 to 1.2 eq.) followed by TEA or NMM (2 to 3 eq.) at room temperature under argon, the reaction mixture is stirred at room temperature until completion. Then the reaction is quenched with water, the layers are separated. The organic layer is dried over Na2SO i, filtered and evaporated to dryness. Alternatively, the reaction is concentrated in vacuo, the residue is partionned between EtOAc or a mixture of EtOAc/nBuOH and a saturated aqueous NH4C1 solution or water. The layers are separated, the organic layer is dried over Na2S04, filtered and evaporated to dryness. Then the residue is purified by chromatography on silica gel to afford the expected Intermediate.
