実験手順

To a solution of (3R,9aS)-tert-butyl 3-(3-cyano-4-fluoro-2-methylphenyl)hexahydro-1H-pyrazino[1,2-a]pyrazine-2(6H)-carboxylate [I-18A](250 mg, 0.668 mmol) and 3-(1H-tetrazol-1-yl)-6,7-dihydro-5H-cyclopenta[c]pyridine-7-carboxylic acid [I-65] (201 mg, 0.868 mmol) in DMF (4 mL) was added HATU (381 mg, 1.00 mmol) followed by addition of diisopropylethylamine (350 μL, 2.00 mmol). The resulting solution was stirred at rt for 1 h. Ethyl acetate (100 mL) was added and the mixture was washed with saturated sodium bicarbonate (3×100 mL), dried over sodium sulphate, concentrated and the residue was purified by preparative TLC eluting with 10% methanol/methylene chloride to give the title compound. LC/MS: (M+1)+: 588.2.
