Reaction Steps

To trans-N1-(4-(6-(3-fluorobenzylamino)pyrazin-2-yl)pyridin-2-yl)cyclohexane-1,4-diamine (19 mg, 0.048 mmol) was added NMP (0.6 ml), acetic acid (0.042 ml, 0.726 mmol) and benzaldehyde (10.27 mg, 0.097 mmol). The resulting reaction mixture was stirred overnight at ambient temperature. To the stirred reaction mixture was added sodium triacetoxyborohydride (41.0 mg, 0.194 mmol) and the resulting mixture was stirred overnight (24 hours) at ambient temperature. To the reaction mixture then was added additional sodium triacetoxyborohydride (21.0 mg, 0.099 mmol) and the resulting mixture was stirred for an additional 2 more hours. To the crude mixture then was added 0.8 ml of DMSO, filtered and purified by prep LC. After lyphilization, 7.0 mg of the title compound was obtained as a TFA salt.
