Participants

Reaction Steps

Add NaBH3CN (63 mg, 1.00 mmol) to a solution of 6-(5-aminomethyl-5,6,7,8-tetrahydro naphthalen-1-yloxy)-nicotinamide (intermediate 20, 148 mg, 0.500 mmol) and cyclohexanone (98 mg, 1.00 mmol) dissolved in 5% AcOH/MeOH (5 ml) and stir at ambient temperature for 16 hours. Concentrate the reaction mixture and redissolved in EtOAc. Wash the EtOAc solution with 5% aq. KOH and brine before drying (MgSO4) and concentrating. Purify on silica gel (5% (1N NH3/MeOH)/DCM) to obtain 145 mg of the title compound as a white foam.
