実験手順
0.40 g (2.12 mmol) 4-amino-3-chloro-5-nitrophenol were placed in 5 mL DCM. 0.44 mL (2.54 mmol) DIPEA and 0.26 mL (2.54 mmol) tetrahydro-2H-pyran-4-carbonyl chloride were added and at RT the mixture was stirred for 2 h. A further 0.26 mL (2.54 mmol) tetrahydro-2H-pyran-4-carbonyl chloride were added and the mixture was stirred overnight at RT. The reaction mixture was diluted with DCM and washed with water. The organic phase was evaporated down i.vac.
