With N-ethyl-N,N-diisopropylamine; In 1-methyl-pyrrolidin-2-one; for 20h;Combinatorial reaction / High throughput screening (HTS); | Each resin from Step 3 was distributed into 24 fritted syringes (Torvig, 50 mg each, 50 mumol), for a total of 96 syringes, and was swelled in NMP (1 mL) for 30 min. The solvent was removed by filtration. Twenty-four solutions of the building blocks listed below (10 mmol each) and DIBA (3.5 mL, 20 mmol) in NMP (10 mL) were prepared. 3 mL of the 24 solutions was added to the 24 syringes for each resin from Step 3, accordingly. The suspensions were then shaken for 20 h on a Titer Plate Shaker. The reaction mixture was filtered and washed 5 times with methylene chloride (5 mL), 3 times with THF (5 mL), 3 times THF/H2O (3/1 v/v, 5 mL), and 3 times with THF (5 mL). The resins were then dried overnight under vacuum. |
