Methyl 4-methyl-5-thiazolecarboxylate Use and Manufacturing

General procedure: A solution of amine 2 (5 mmol) in THF (3 mL) was added dropwise over 20 min to a solution of t-BuONO (7.5 mmol) and DMSO (0.5 mmol) in THF (7 mL) at 30 °C. The mixture was stirred at 30 °C until the starting materials 2 were consumed (monitored by TLC). The solvent was evaporated, and the yields of the low boiling point products were determined by GC; the high boiling point products were isolated by column chromatography on silica gel (hexane/ethyl acetate).Silver reagent (0.1 mmol), phosphine ligand (0.1 mmol), deuterated water (0.4 g, 20 mmol), General procedure: A solution of amine 2 (5 mmol) in THF (3 mL) was added dropwise over 20 min to a solution of t-BuONO (7.5 mmol) and DMSO (0.5 mmol) in THF (7 mL) at 30 C.
