HCID 407366HCID 407366, compound

Procedure

Diethanolamine (10.84 g) was heated with concentrated H2SO4 (20.13 g) at about 10-15 mm vacuum (house vacuum) and at a temperature in the range of about 175-180° C. for 5.5 h. The resulting solution was cooled to ambient temperature and stirred over the weekend under nitrogen. The resulting light brown solution was determined by 1H NMR to contain the title compound in solution.
