MIAO, Hua, WO2015/89337, A1, (2015) [0617j To a solution of 4-bromo-2-methylbenzonitrile (3.0 g, 15 mmol) in anhydrous THF (20 mL) under nitrogen at 0 °C was added 1.0 M solution of borane in THF (46 mL). The reaction mixture was stirre d at 0 °C for 1 h, and heated at 80 °C overnight. The reaction mixture was cooled to 0 °C and slowly quenched with MeOH, concentrated in vacuo. The crude product was treated with EtOAc (20 mL) and 4 M of HC1 in 1,4-dioxane (8.0 mL, 32 mmol) for 5 mm. The solid was filtered, rinsed with diethyl ether, dried to give the title compound as a white powder (3.24 g, yield: 100percent).
