=Objective= To optimize the reaction from Exp099 to make this [|Ugi product] using Mettler Toledo's automated Minimapper. Forty eight reactions are run in parallel using four reactant (2.0M in methanol) in different solvents / concentration. =Procedure= Make up 2M methanol solutions (25mL each) of starting materials - Furfurylamine (4.418mL), Boc-glycine (8.759g) and tert-butyl isocyanide (5.655mL) and 2.077M Benzaldehyde solution (5.275mL / 25mL methanol) The following are added in this order in a reaction tube equipped with a filtration frit 1) The additional solvent (200uL methanol) 2) The benzaldehyde solution 3) The Furfurylamine solution 4) The Boc-Glycine solution 5) The tert-butyl isocycanide solution

concentration - 0.5M, 0.25M and 0.1M reagent excess - 1.0 and 1.2 equivalents solvent (for 0.25 and 0.1 conc only): ethanol, acetonitrile, THF Limiting reagent conc : 0.2mmol

19:40 Started the run with minimapper. 20:50 Minimapperr completed the run.. 21:00 Set the miniblock (red) on the shaker. 17:00 Removed the miniblock from the shaker and vacuumed off excess solvent. 17:10 Set the miniblock on the minimapper and programmed it to deliver methanol (1mL) to each reaction tube. 17:30 Minimapper completed adding methanol to the reaction tubes. 17:32 Placed the miniblock on the shaker and started shaking at 400 rpm for 15 min. 17:50 Removed from the shaker and vacuumed off the solvent from the reaction tubes. 18:00 Set the miniblock on the minimapper and programmed it to deliver methanol (1mL) to each reaction tube for washing a second time. 18:25 Minimapper completed adding methanol to the reaction tubes. 18:30 Placed the miniblock on the shaker and started shaking at 400 rpm for 15 min. 18:45 Removed from the shaker and vacuumed off the solvent from the reaction tubes. The miniblock is let connected to the house vac for 30min. 19:15 The miniblock was disconnected from the house vac and placed in a desiccator connected to a high-vac.
