Reaction Steps
CDI (89 mmoles) is added to a solution of the compound obtained in Step A (44.5 mmoles) and DMAP (44.5 mmoles) in DCM (250 ml). After stirring for 4 hours at ambient temperature, the reaction mixture is diluted with 300 ml of DCM and then washed with 2M HCl solution (5×200 ml). The organic phase is dried over magnesium sulphate, filtered and evaporated to dryness to yield the title product in the form of an orange solid, which is used directly in the next Step.
