Hydrogenation of the enantiomerically pure 1-(alpha-methylbenzyl)-3-(hydroxymethyl)pyrrolidine (I) in the presence of Pearlman's catalyst and di-tert-butyl dicarbonate produced the N-Boc pyrrolidine (II). Reaction of (II) with methanesulfonyl chloride, followed by condensation of the resulting mesylate (III) with (S)-alpha-methylbenzylamine (IV) in toluene at 150 C in a sealed tube afforded the aminomethyl pyrrolidine derivative (V). Then, acidic cleavage of the Boc protecting group yielded pyrrolidine (VI).
