Example 1 Preparation of 2-bromo-8-fluoro-4,5-dihydro-1H-azepino[5,4,3-cd]indol-6(3H)-one (Formula IV) 8-fluoro-4,5-dihydro-1H-azepino[5,4,3-cd]indol-6(3H)-one (Formula V) 100 gm was dissolved in dichloromethane (1000 ml). Pyridinium tribromide (200 gm) was added in the above solution and stirred at 0-5 C. until completion of reaction. Once reaction was complete saturated sodium carbonate solution (500 ml) was added and stirred for 2 hours. The solid was filtered and washed with water (200 ml). The wet cake was taken in acetonitrile (150 ml) and DIPE (150 ml) and stirred at RT for 1 hour. The obtained solid was filtered and washed with acetonitrile (50 ml). The material was dried at 50 C. to get 2-bromo-8-fluoro-4,5-dihydro-1H-azepino[5,4,3-cd]indol-6(3H)-one (Formula IV) (110 gm).

Application of 1408282-26-7, A common heterocyclic compound, 1408282-26-7, name is 8-Fluoro-4,5-dihydro-1H-azepino[5,4,3-cd]indol-6(3H)-one, molecular formula is C11H9FN2O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

8-Fluoro-4,5-dihydro-lH-azepino[5,4,3-cd]indol-6(3H)-one, (lOg; 49.0 mmol) is suspended at ambient temperature in 1 L reactor in 225 mL of dichloromethane/tetrahydrofuran mixture (1/3). Obtained suspension is cooled to 5C while stirring and THF solution of pyridinium tribromide is added dropwise (17.22 g; 53.9 mmol in 75 mL THF). Obtained suspension is stirred at 5C for 2 hours until conversion is complete. Water (100 mL) is added to obtain clear orange solution. Solution is concentrated under vacuum until crystallization occurs. To obtained suspension 750 mL of saturated Na2C03 is added and suspension is stirred for 1 hour at ambient temperature. Obtained crystals are filtered, washed with water (100 mL) and dried in vacuum oven at 55C for 4 hours to obtain 11.3 g of 2-bromo-8-fluoro-4,5-dihydro-lH-azepino[5,4,3-cd]indol-6(3H)-one.
