Reaction Conditions

Reaction Steps

4-Chloro-2-(3-methyl-pyrazol-1-yl)-benzaldehyde (446 mg, 2.03 mmol) from Step 1 was dissolved in MeOH (14 mL) and cooled to 0° C. NaBH4 (175 mg, 4.61 mmol)) was added portionwise. The reaction mixture was allowed to warm to RT, and after 90 min was quenched with acetone. The MeOH was removed in vacuo. The residue was partitioned between water and EtOAc and then extracted. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by normal phase silica gel column chromatography (EtOAc/heptane) provided the title compound.
