Workup

  1. additionAfter 22 hours the crude reactions were diluted with 3 x 1 uL 0.5 M AcOH in DMSO (containing PhPh as an internal standard). The reactions were mixed after each dispense operation.
  2. aliquotMosquito(R) was used to transfer 1 uL of each quenched reaction from the 1,536-well reaction plate to 384-well analytical plates containing 60 uL DMSO for analysis.
