実験手順: BOC proline (CAS 15761-39-4) and 2-(R)-Methyl-pyrrolidine hydrochloride (CAS 135324-85-5) are coupled in a manner substantially analogous to General Procedure D in dichloromethane to give 2(S)-(2(R)-Methyl-pyrrolidine-1-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (233179). The material is deprotected by stirring in dichloromethane at 5-10° C. while trifluoroacetic acid (10 eq) is added and then stirred at room temperature for 18 hours. Reaction is concentrated and dissolved in H2O. The pH is adjusted to 8-9 with K2CO3, and the aqueous layer is extracted several times with CH2Cl2. The extracts are combined, dried (Na2SO4) and concentrated in vacuo to give (2(R)-Methyl-pyrrolidin-1-yl)-pyrrolidin-2-yl-methanone. A 1 M Lithium Aluminum Hydride/THF solution (3 eq.) is diluted with an equal volume of THF and stirred under N2. A THF solution of (2(R)-methyl-pyrrolidin-1-yl)-pyrrolidin-2-yl-methanone is added dropwise, allowing the reaction to mildly exotherm. The reaction is stirred at 40° C. for 45 minutes, then at room temperature 18 hours. Reaction is cooled in an ice bath and is quenched with H2O (3 eq.), 4 N NaOH (3 eq.), then H2O (9 eq.) while keeping reaction temperature less than 15° C. Reaction is stirred overnight, is filtered and the precipitate is washed three times with THF. The filtrate and washes are combined and concentrated to give 2-(R)-methyl-1-(2-(S)-pyrrolidinylmethyl)pyrrolidine. MS (ES+) 169.3 (M+H)+ Intermediate is used as such or is purified by SCX chromatography or distillation. the reaction The reaction is stirred at 40° C. for 45 minutes at room temperature 18 hours Reaction is cooled in an ice bath reaction temperature less than 15° C Reaction is stirred overnight is filtered the precipitate is washed three times with THF concentrated
