Yield: 93%
Reaction Conditions:
with diammonium hydrogenphosphate in sulfolane at 25 - 175; under 1034.32 Torr; for 22 h;Product distribution / selectivity;
Steps:
3.e
Picric acid (10.0 g, 43.8 mmol), diammonium hydrogen phosphate (11.6 g, 87.6 mmol) and dry sulfolane (40 ml) are placed in a glass-lined, stainless steel reactor to form a 1.1M concentration reaction slurry. The reactor is sealed and the reaction slurry is stirred with heating for 2 hr as the temperature increases from 25 to 175° C. (20 psi pressure). The temperature is maintained at 175° C. and stirring is continued for an additional 20 hr. The cooled reaction mixture is mixed with water (400 ml) and the insoluble material is collected, washed with water and dried to produce picramide in 93% yield (Table 2, entry 5).
