Ugi NMR Analysis
To synthesize a

. The target compound was ranked 159 in the
. The purpose of this experiment is to synthesize an anti-malarial compound based on the inhibition of falcipain-2, as described in this
To a one dram vial, charged with methanol (1 ml), 5-methyl-2-furylmethylamine, benzaldehyde, 3-(4-methoxyphenyl)propionic acid and tert-butyl isocyanide. (0.5mmol each) was added in that order. After each addition, the resulting solution was vortexed for 15 seconds and confirmed that a homogeneous solution had been obtained. The vial was capped tight and left at room temperature.

After the vial set out at room temperature for a day and was sonicated, no Ugi product was formed.
15:18- Charged vial with 1ml of methanol
15:23- Weighed out the acid.
15:26- Added amine to vial and vortexed for 15 seconds. A clear solution was achieved.
15:28- Added the aldehyde to the vial and vortexed for 15 seconds. A clear solution was achieved.
15:30- Added acid to the solution and vortexed for 15 seconds and the acid was dissolved. A clear solution was achieved.
15:32- Added isocyanide to the vial and vortexed for 15 seconds. A clear solution was achieved.
15:34- The vial was left to sit at room temperature for a day. The liquid is an amber/brown color.
15:39- Took picture of the vial.
15:25- Took picture of the vial. No precipitate has formed yet.
15:38- Put the vial into the sonicator for ten minutes.
15:48- Removed the vial from the sonicator. No precipitate has formed.
15:58- Took another picture of the vial after sonication.
