Reaction Steps

To a solution of ethyl 2-ethyl-2H-indazole-5-carboxylate (step-1 of Example 13, 150 mg, 0.69 mmol) in THF (10 mL) was added LiAlH4 (26 mg, 0.69 mmol) at 0° C. The mixture was stirred at room temperature for 1 hr. The mixture was quenched with saturated aqueous NH4Cl. The precipitate was filtered off. The filtrate was concentrated to give the titled compound (131 mg, quant) as an orange colored oil.
