The pyrrolidine intermediate (VII) has been obtained as follows: The acylation of N-Boc-pyrrolidine-3(R)-amine (I) with chloroacetyl chloride (II) and TEA in dichloromethane gives the acetamide (III), which by treatment with ammonia in methanol/water yields the glycinamide (IV). The reaction of (IV) with protected S-methylisothiourea (V) in methanol affords the protected guanidine (VI). The N-Boc deprotection of (VI) by means of HCl in ethyl acetate/acetonitrile affords the target pyrrolidine intermediate (VII).
