Procedure
To a stirred solution of t-butyl nitrite (271 mg, 0.312 ml, 2.63 mmol) in DMF (15 ml) at 60°-65° C. was added 7-allyloxy-3-amino-1,2,4-benzotriazine- 1,4-dioxide 23 (205 mg, 0.875 mmol) in small portions over 5 min. After 30 min additional t-butyl nitrite (271 mg, 0.312 ml, 2.63 mmol) was added, and shortly thereafter the deep red solution effervesced and lightened appreciably in color over a period of a few minutes. After an additional 30 min the resultant orange solution was reduced under vacuum to a brown solid which was sequentially flash chromatographed (10% EtOAc/CH2Cl2) and crystallized (CH2Cl2 /petroleum ether) to give 72 mg (38% yield) of the product 24 as light orange crystals, mp 147°-148° C.
Workup
- waitlightened appreciably in color over a period of a few minutes
- customchromatographed (10% EtOAc/CH2Cl2)
- customcrystallized (CH2Cl2 /petroleum ether)
