Reaction Steps

128 mg (0.51 mmol) of (RS)-S-(4-aminophenyl)-N-(ethoxycarbonyl)-S-ethyl sulfoximide and 150 mg (0.53 mmol) of (2R,3R)-3-[(5-bromo-2-chloropyrimidin-4-yl)oxy]-butan-2-ol in 2 ml of acetonitrile are mixed with 0.12 ml of a 4N solution of HCl in dioxane. The batch is stirred for 2 days at 60° C. The solvent is removed, and the residue is purified by chromatography (DCM/EtOH 95:5). 43 mg (0.09 mmol, corresponding to 17% of theory) of the product is obtained.
