(2S)-propane-1,2-diamine

Conditions: temp:20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To 62.9 parts of (S)-1,2-propanediamine under a nitrogen atmosphere (temp. 0°-5° C.) was added dropwise over 7 hours a solution of 80.84 parts of 4-methylbenzenesulfonyl chloride in 1689 parts of dichloromethane. After stirring overnight at 20° C., the reaction mixture was washed with 250 parts of water (3×). The organic layer was separated, dried, filtered and evaporated. About 1 gram of the thus obtained product was recrystallized from 2-propanol. After cooling to 0° C,, filtering and drying, about 0.30 parts of crystals suitable for seeding were obtained. The remainder of the product was dissolved in 4-methyl-2-pentanol by heating just below the reflux temperature. The mixture was allowed to cool slowly and at about 30° C. was seeded with the previously obtained crystals. After further cooling to 0° C., the precipitate was filtered off and triturated with 2,2'-oxybispropane. The crystals were filtered off, dried in vacuo, yielding 50.75 parts (52.4%) of (S)-N-2-aminopropyl-4-methylbenzenesulfonamide; mp. 82°-86° C.; [α]20D =-1.10° (c =1% in methanol) (interm. 1). the reaction mixture was washed with 250 parts of water (3×) The organic layer was separated dried filtered evaporated About 1 gram of the thus obtained product was recrystallized from 2-propanol After cooling to 0° C filtering drying, about 0.30 parts of crystals suitable for seeding were obtained by heating just below the reflux temperature to cool slowly and at about 30° C. After further cooling to 0° C. the precipitate was filtered off triturated with 2,2'-oxybispropane The crystals were filtered off dried in vacuo
