Versuchsvorschrift

Mesityloxyacetic acid (89.3 g; 460 mmol), diisopropylethylamine (297.1 g; 2.3 mol), tert-butyl amino(imino)methylcarbamate (76.8 g; 480 mmol), and 1-hydroxybenzotriazole monohydrate (62.4 g; 460 mmol) were dissolved in N,N-dimethylformamide (1.0 L), 2-(1H)-benzotriazol-1-yl-1,1,3,3-tetramethyluronium hexafluorophosphate (183.1 g; 460 mmol) was added thereto, and the mixture was stirred for 25 hours at room temperature. The precipitated crystals were collected by filtration, washed with ethyl acetate and then dried to give 135.2 g of the title compound (yield 88%).
