Reaction Steps

A solution of 2-methyl-1′-(3-methyl-4-nitro-phenyl)-[1,3′]bipyrrolidinyl (Intermediate (iii) obtained above, 2.23 g, 7.7 mmol) in MeOH was de-aerated and nitrogen was introduced. To this solution was added Pd—C (10%). This mixture was stirred under H2 atmosphere at r.t. for 8 h. TLC (10% MeOH in DCM) and LC/MS showed the reaction was complete. The mixture was passed through a Celite pad, rinsed with methanol. The filtrate was concentrated to dryness, and further dried under high vacuum to yield a reddish brown liquid after drying under high vacuum to obtain the title compound as a gummy black liquid, 1.73 g (86%). This material was used in the next step without further purification and storage. MS: 260 (M+H+).
