To a solution of N-(2,6-dimethylphenyl)-2-{4-[4-(2-methoxyphenyl)-3-oxobutyl]piperazin-1-yl}acetamide (100 mg, 0.23 mmol) in ethanol (2 mL) was added sodium borohydride (50 mg), and the mixture was stirred for 16 hours. Excess borohydride was then quenched by the addition of saturated ammonium chloride solution. Dichloromethane (20 mL) was added, the mixture shaken, and the organic layer was separated, washed with water and concentrated under reduced pressure. The residue obtained was purified by preparative TLC using 10% methanol in dichloromethane as mobile phase to afford N-(2,6-dimethylphenyl)-2-{4-[3-hydroxy-4-(2-methoxyphenyl)butyl]piperazin-1-yl}acetamide, a compound of Formula I.
