== =Objective= To synthesize Ugi adducts following the EXPLAN005. The compounds will contribute toward a library for enoyl reductase inhibitors. =Procedure= A Ugi reaction was carried out in a 1.5 ml Eppendorf tube. In the tube, methanol (500uL), methylamine (2.0M solution in methanol, 0.25mmol, 125uL), o-tolualdehyde (0.25mmol, 28.9uL), acetic acid (0.25mmol, 14.31uL), and //p//-toluenesulfonylmethyl isocyanide (0.25mmol, 48.8mg) were added, in that order. After each addition the solution was vortexed for 15s and made sure a homogeneous solution was obtained. The Eppendorf tube was left at room temperature.

=Results=

=Discussion= The solution remained clear after adding all of the compounds and allowing it to sit for 24 hours. =Conclusion= A Ugi product was not obtained.
