Reaction Steps

A solution of 5.90 g of 1-formyl-3-(α-phenyl-2-tolyl)pyrrolidine of Example 59 in 40 ml of dry THF is added dropwise to a suspension of 2 g LiAlH in 20 ml of dry THF and the mixture is refluxed for 4 hours. After cooling and hydrolyzing with 20 ml of H2O the organic phase is separated and the residue is extracted with ether. The combined organic phase is washed with water, dried (Na2SO4), and concentrated to an oil. This oil is dissolved in 10 ml of acetone and made acidic with a slight excess of HCl/ether. After addition of 200 ml of ether the product is collected and recrystallized from acetone/ether (35/70 ml) to provide 1-methyl-3-(α-phenyl-2-tolyl)pyrrolidine, mp 149.5°-151° C.
