実験手順

(+)-trans-1-[2-Hydroxy-3-(2-hydroxymethyl-1-methyl-pyrrolidin-3-yl)- -4,6-dimethoxyphenyl]-1-ethanone (compound 13), was prepared from (+)-trans-[1-Methyl-3-(2,4,6-trimethoxy-phenyly-pyrrolidin-2-yl]-methanol using the procedures described in examples 6 & 7. Compound 13, (0.7 g, 2.2 mmol) was reacted with methyl 2-chlorobenzoate (1.15 g, 6.75 mmol) in dry DMF (15 mL) in the presence of NaH (50%, 0.54 g, 11.25 mmol), using the procedure described in example 8 to afford the title compound(4).
