Reaction Conditions

Reaction Steps

[4-(S)-(3-Cyclopropylmethoxy-4-methoxyphenyl)-3-(S)-methylpyrrolidin-3-yl]methanol (100 mg, 0.34 mmol) was dissolved in CH2C2 (1.7 mL), and the solution was cooled to 0° C. DIEA (144 μL, 0.82 mmol) was added, followed by benzyloxyacetyl chloride (114 μL, 0.72 mmol). The reaction was allowed to warm to room temperature slowly and stirred for 18 hours. Water was added (0.25 mL) and the reaction was stirred for 1.5 hours. CH2C2 was added and the mixture was washed once with water, twice with 1N HCl, once with water, twice with 6% NaHCO3, then dried over Na2SO4 and concentrated in vacuo. The residue was dissolved in THF (1 mL) and cooled to 0° C. A solution of LiOH in water (1.36M, 1 mL, 1.36 mmol) was added and the hydrolysis was allowed to proceed at 0° C. for 4 hours. The reaction mixture was quenched with saturated NH4Cl, and the THF was removed by concentration in vacuo. The residue was resuspended in CH2C2, and washed twice with 6%. NaHCO3, dried over Na2SO4 and concentrated in vacuo.
