実験手順

To a solution of 4-(2-cyano-5,7,7,10,10-pentamethyl-7,8,9,10-tetrahydro-5H-5,13-diazabenzo[4,5]cyclohepta[1,2-b]naphthalen-12-yl)benzoic acid methyl ester (33) (R4=CH3, Z=H, 12.3 mmol) in DMF (15 mL) and THF (45 mL) is added 2 N NaOH (18.5 mmol) at room temperature. The reaction mixture is stirred at the same temperature for 1 day. The mixture is acidified by 1 N HCl (30 mL), diluted with H2O, and extracted with EtOAc. The organic layer is dried over MgSO4 and evaporated in vacuo. The resulting solid is washed with hexane and Et2O to give (34) (R4=CH3, Z=H): 1H-NMR (CDCl3) δ: 1.08 (3H, s), 1.15 (3H, s), 1.28 (3H, s), 1.32 (3H, s), 1.61-1.72 (4H, m), 3.28 (3H, s), 6.90 (1H, s), 6.63 (1H, s), 6.99 (1H, d), 7.41 (1H, dd), 7.57 (1H, d), 7.90 (2H, d), 8.17 (2H, d).
