Procedure

A solution of 6-[(7-hydroxyquinolin-4-yl)oxy]-N,2-dimethyl-1-benzofuran-3-carboxamide 123-A (1 g, 2.9 mmol), 2-(bromomethyl)oxirane (467 mg, 3.4 mmol) and Cs2CO3 (1.4g, 4.2 mmol( in CH3CN (25 ml) was heated to 65° C. for 3 hours. The solution was extracted with EtOAc. N,2-dimethyl-6-{[7-(oxiran-2-ylmethoxy)quinolin-4-yl]oxy}-1-benzofuran-3-carboxamide 123-B (1.1 g) was isolated by a silica gel column using 1-5% MeOH in CH2Cl2 To a solution of 123-B (150 mg, 0.35 mmol) in THF (5 ml) was added a solution of methylamine in MeOH (1 N, 1 ml). The solution was heated to 65° C. for 2 hours. The crude product was purified by HPLC (10-40% CH3CN/H2O over 30 min.) to give 6-({7-[2-hydroxy-3-(methylamino)propoxy]quinolin-4-yl}oxy)-N,2-dimethyl-1-benzofuran-3-carboxamide 123.
