Participants

Reaction Steps

4-(1-(5-(7,7-Dimethyl-4,5,6,7-tetrahydro-3H-imidazo[4,5-c]pyridin-2-yl)-2,4-dimethylbenzoyl)piperidin-4-yl)benzonitrile (0.12 g, 0.26 mmol) (intermediate prepared in the synthesis of compound 451), DMF (4 mL), acetic acid (69 μL, 1.21 mmol), sodium triacetoxyborohydide (0.11 g, 0.52 mmol) and acetone (0.50 mL, 6.8 mmol) were mixed and stirred at room temperature for 2 hours. The reaction was carefully quenched with water (10 mL) and the mixture was extracted with ethyl acetate (60 mL) and the organics was dried (Na2SO4), filtered and concentrated in vacuo. The crude product was purified by preparative TLC (DCM/10% MeOH) followed by a second preparative TLC (ethyl acetate/5% MeOH) to obtain the title compound as a white powder (4.1 mg, 8.1%). m/z (ES+) 510 (M+H)+.
