実験手順

A solution of (4-morpholin-4-ylmethyl-phenyl)-piperazin-1-yl-methanone (0.128 g) in methanol (7.5 mL) was treated with (1-ethoxy-cyclopropoxy)-trimethyl-silane (1.5 mL), acetic acid (0.2 mL), and NaBH3CN (˜400 mg). The mixture was heated at 60° C. for 18 h, and then was cooled to room temperature and concentrated. The residue was diluted with 1 N NaOH and extracted with CH2Cl2. The organic layer was dried (Na2SO4) and concentrated. The residue was purified by column chromatography (SiO2) to yield the title compound.
