Reaction Steps

1 gram of 6,7,8,9-tetrahydro-5H-dibenz(b,i)(1,6)oxazecine was mixed with 4 ml formic acid and 3.8 ml of 37% formalin. This mixture was heated for 1 hour at 100° C. After cooling 0.5 ml of concentrated hydrochloric acid was added and the reaction mixture was evaporated. The residue was then dissolved in dilute NaOH, and the mixture extracted with ether. The ether extract was washed, dried and evaporated to dryness.
