Reaction Steps

In 20 ml of DMF was dissolved 100 mg of 2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one and the solution then ice-cooled. Then, to the resulting solution were added 0.125 ml (1.5 equivalent) of 1,5-dibromopentane and 29.4 mg (1.2 equivalent) of a 60% sodium hydride oil dispersion and the mixture was stirred for 1.5 hour with ice-cooling. Thereafter, the reaction solution was reacted and/or treated and purified in the same manner as in Reference Example 1 to give 133 mg (yield: 69.5%) of the title compound.
