Procedure
A mixture of 8-(methyloxy)-3,4-dihydro-1,4-benzoxazepin-5(2H)-one (Preparation 25) (7.98 g, 41.3 mmol) and hydrobromic acid (100 ml, 1842 mmol) was stirred and heated at 110° C. for 7 hours. Then the reaction mixture was evaporated and azeotroped twice with 150 ml of ethanol to give the title compound (8.66 g) light brown solid which was used without purification. MS (ES) C9H9NO3 requires 179; found 180 [M+H]+.
