Reaction Steps

To a mixture of methyl 2-[5-(benzyloxy)-2-isopropoxyphenyl]-3H-imidazo[4,5-b]pyridine-5-carboxylate (0.45 g) in tetrahydrofuran (10 ml) was added lithium aluminum hydride (82 mg) under ice-cooling. The reaction mixture was stirred at room temperature for 1 hr, and water was added. The insoluble material was removed by filtration, and the filtrate was concentrated to give the title compound (0.26 g, yield 61%) as colorless crystals. melting point 167-168° C. purity 99%. M+H: 390. 1H NMR (CDCl3) δ: 1.52 (6H, d, J=6.0 Hz), 4.74-4.82 (1H, m), 5.16 (2H, s), 7.00-7.50 (8H, m), 8.06 (1H, d, J=8.1 Hz), 8.19 (1H, d, J=3.0 Hz).
