Sodium Hydroxide → (R)-1-[(3R,5R)-5-(4-chlorophenyl)morpholin-3-yl]ethanol

Participants

Reaction Steps

Trimethylsilyl iodide (3.07 mL) was added to a dichloromethane (20 mL) solution of (3R,5R)-3-((R)-1-benzyloxyethyl)-5-(4-chlorophenyl)morpholin (1.44 g). Stirring was continued for 10 hours at room temperature. Additional trimethylsilyl iodide (3.07 mL) was added, and the resultant was stirred at room temperature for 4 days. Additional trimethylsilyl iodide (3.07 mL) was further added, and stirring was continued for 1 day. Additional trimethylsilyl iodide (3.07 mL) was further added, and stirring was continued for 10 hours at room temperature. A 5 N sodium hydroxide solution was added, and the organic layer was partitioned. The organic layer was dried over anhydrous magnesium sulfate. The resultant was purified with silica gel column chromatography (heptane/ethyl acetate). The title compound (903 mg) was obtained. The physical property values are as follows.
