20:00 Powered on the water/glycol temperature bath and set it to 40C.
20:30 Made-up solution of the Ugi product 176C in ethyl acetate in a half dram vial labeled 1, made sure some of the solid remained undissovled even after vortexing it for a min.
20:40 Made-up a solution of phenanthrene-9-carboxaldehyde in THF, labeled 2, made sure some of the solid remained undissovled even after vortexing it for a min.
20:45 Placed the vials in a the water/glycol bath at 40C
21:30 Changed the temperature setting of the bath to 25C
22:00 Temp recorded- 25C
23:30 Removed the vial from water/glycol temp bath, centrifuged it.
23:45 Carefully pipetted out the supernatants (~100uL) in to a one dram vials, labeled 1A and 2A containing ~800uL DMSO-d6. Capped the vials and vortexed it.
