Reaction Steps

2-chloro-4-hydroxy-3-(5-hydroxytetralin-6-yl)-5-phenyl-7H-thieno[2,3-b]pyridin-6-one (4.0 g, 9.44 mmol) was dissolved in a mixture of methanol/tetrahydrofuran (25 ml/25 mL). Sodium methoxide solution (30% in methanol) (1.75 mL, 9.44 mmol) was slowly added followed by water (15 ml). Organic solvents were removed under reduced pressure. The remaining aqueous solution was lyophilized to give a grey solid (4.80 g, 100%, compound crystallized with 4 water molecules).
