Reaction Steps
250 mL flask was charged with 6-benzyl-4-methoxy-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (4.08 g, 16.0 mmol), 10% palladium on charcoal (400 mg) and methanol (100 mL). The reaction was evacuated and purged with hydrogen three times, and hydrogenated (1 atm) overnight. The mixture was filtered through a “Dry disk” membrane filter, and concentrated in vacuo to give an orange oil (2.56 g).
