After the reaction mixture has been cooled, 300 ml of methyl tert-butyl ether are added, the mixture is washed three times with saturated Na2S2O3 solution and dried over MgSO4 and the solvents are then removed under reduced pressure. This gives 2.64 g of 4-iodomethyl-5-methyl-2-(4-(2-propyl)-phenyl)-oxazole as a yellowish solid. C14H16INO (341.19), MS(ESI): 342 (M+H+).
