Reaktionsschritte

Pyridine (1.2 mL, 15.4 mmol) was added to a stirred solution of commercially available 4-chloropyridin-2(1H)-one (100 mg, 0.77 mmol), 4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenylboronic acid Part C (278 mg, 1.16 mmol), and copper (II) acetate, monohydrate (154 mg, 0.77 mmol) in CH2Cl2 (7 mL) and MeOH (0.7 mL). The reaction mixture stirred at RT under the presence of air overnight (21 hours). The reaction mixture was diluted with CH2Cl2, washed with IN HCl, sat. NaHCO3, dried (Na2SO4), and concentrated. The crude product was purified using preparative HPLC (C18 column/10:90:0.1 to 90:10:0.1 MeOH—H2O-TFA) to afford the desired product 4-chloro-1-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyl)pyridin-2(1H)-one 9D (169 mg, 0.49 mmol, 62.8% yield) as a brown gum. LC/MS 324 (M+H)+, tR 0.75 min (method 5)
