Reaction Steps

Title compound was prepared following general procedure 3 starting from Intermediate 24 (168 mg; 0.6 mmol) and Intermediate 25 (182 mg; 0.6 mmol). The reaction mixture was diluted with EtOAc, washed with water and brine and evaporated under vacuum. Purification by silica column chromatography (c-Hex/(DCM/EtOAc 1:1), 90/10 to 50/50) afforded the title compound as a yellow oil. LC/MS (method B): 565.2 (M+H)+. HPLC (Method A) Rt 5.00 min (Purity: 95.4%).
