Procedure

A mixture of methyl 4-(4-(chloromethyl)-5-methyloxazol-2-yl)benzoate (2.0 g, 7.55 mmol, 1.00 equiv), lithium 4-(3-morpholinopropyl)benzenesulfinate (4.0 g, 14.55 mmol, 1.93 equiv) and potassium carbonate (1.35 g, 9.78 mmol, 1.30 equiv) in N,N-dimethylformamide (50 mL) was stirred overnight at 70° C. The product was precipitated by the addition of 150 mL ice and water after the reaction was cooled to room temperature. The solid was collected by filtration, washed with 2×15 mL of water and dried in a vacuum oven to give 2.8 g (74%) of methyl 4-(5-methyl-4-((4-(3-morpholinopropyl)phenylsulfonyl)methyl)oxazol-2-yl)benzoate as a white solid. LC-MS: (ES, m/z): 499 [M+H]+, 115.
