Participants

Reaction Steps

4-(4,8-dimethyl-7-oxo-7,8-dihydro-pyrido[2,3-d]pyrimidin-2-yloxy)-butyraldehyde (78.4 mg, 0.30 mmol) and 1-(7-fluoro-naphthalen-1-yl)-piperazine trifluoroacetic acid (105 mg, 0.306 mmol) were combined in methylene chloride and triethylamine (63 mg, 0.63 mmol) was added. The mixture was stirred in a vial over sieves for 10 min. Sodium triacetoxyborohydride (89 mg, 0.420 mmol) was added and the reaction was stirred overnight. The reaction was quenched slowly with water and the mixture was filtered. The residue was partitioned between CH2Cl2 and water. The organic layer was washed with water and concentrated. Purification by liquid chromatography (MPLC, gradient of 100% CH2Cl2 to 100% of a 10% MeOH in CH2Cl2 solution) gave the title compound as a white foam (89 mg, 0.187 mmol, 62.4%). MS: APCI: M+1: 476.2 (Exact Mass: 475.24).
