Reaction Steps

A solution of 0.32 ml of oxalyl chloride in 7.3 ml of DCM is cooled to −78° C. under a nitrogen atmosphere and a solution of 0.51 ml of DMSO in 3.5 ml of DCM is added dropwise, followed by a solution of 1 g of the compound obtained in step A of EXAMPLE 27 in 7.5 ml of DCM and 0.7 ml of DMSO. The reaction mixture is stirred for 30 minutes at −60° C., 2 ml of triethylamine are then added and the reaction mixture is stirred while the temperature is allowed to rise to RT. It is washed with 1 N HCl solution, with saturated Na2CO3 solution and with water, the organic phase is dried over MgSO4 and the solvent is evaporated off under vacuum to give 1.03 g of the expected product in the form of an oil.
