Use a method similar to the General Procedure 14 to deprotect 3-tert-butoxycarbonyl-7-chloro-6-(3-fluoro-4-isopropylcarbamoyl-benzylamino)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (0.406 g, 0.83 mmol) in 1,4-dioxane (12.8 mL). Purify by SCX chromatography eluting with dichloromethane and dichloromethane/2M ammonia in methanol (1:1) followed by chromatography on silica gel (40 g RediSep column) eluting with dichloromethane/2M ammonia in methanol (99:1 to 90:10 over 30 min) and then dichloromethane/2M ammonia in methanol (90:10 over 30 min; 35 mL/min) to afford 7-chloro-6-(3-fluoro-4-isopropylcarbamoyl-benzylamino)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as a colorless oil (0.3237 g). MS (ES+) m/z: 390.1 (M+H)+. Use a method similar to the General Procedure 2-1, using 7-chloro-6-(3-fluoro-4-isopropylcarbamoyl-benzylamino)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (0.301 g, 0.772 mmol) to provide the title compound as a beige solid (0.328 g, 84%). MS (ES+) m/z: 390.1 (M+H)+.
