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

Procedure: 2,3-dimethylcyclohexanamine (20 μmol) and benzo[d][1,3]dioxole-5-carboxylic acid (1.1 eq) were each dissolved in acetonitrile/dichloromethane (200 μL, 2:1). PS-Carbodiimide resin (2 eq) was loaded into a 1.2 mL 96 well Greiner plate, followed by the addition of amine and acid solutions. Hydroxybenzotriazole (1.1 eq) was dissolved in DMF (100 mL) and was added into the reaction well. The reaction was shaken overnight at room temperature. Once the reaction was completed, PS-Trisamine resin (1.5 eq) was added into the reaction mixture and the solution was allowed to shake overnight at room temperature. Acetonitrile (200 mL) was added into the reaction well, and the top clear solution was transferred into a new plate. The solution was evaporated to give N-(2,3-dimethylcyclohexyl)benzo[d][1,3]dioxole-5-carboxamide. MS (M+H, 276.20). was added into the reaction well to shake overnight at room temperature The solution was evaporated

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

Procedure: To a solution of 2,3-dimethylcyclohexylamine (10.0 g, 79.0 mmol) in tetrahydrofuran (60 mL) was slowly added a solution of 1,3-propane sultone (9.3 g, 75.0 mmol) in THF (20 mL). The solution was stirred at reflux for 2 hours. The reaction mixture was cooled to room temperature. The solid was collected by filtration, washed with THF (50 mL) and acetone (50 mL). The solid was dissolved in 25% EtOH/water (150 mL), and treated with Dowex 50WX8 resin (15 g). The suspension stirred at room temperature for 5 minutes. The resin was removed by filtration. The filtrate was concentrated to dryness under reduced pressure; and the solid residue was suspended in acetone (100 mL).
