Procedure
The process is performed according to the procedure described in Example 4 (step 4.2.). Starting with 2.00 g (12.81 mmol) of 3-methylcarbamoylisoxazol-5-ylmethanol, 2.58 g (12.81 mmol) of 4-nitrophenyl chloroformate, 1.52 g (19.21 mmol) of pyridine and 0.157 g (1.28 mmol) of N,N-dimethylaminopyridine, 2.6 g (63%) of pure product are obtained in the form of a white powder.
Workup
- customare obtained in the form of a white powder
