Reaction Steps

A solution of 4-benzyloxy-1H-pyridin-2-one (1.0 g, 4.97 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (1.86 mL, 12.43 mmol) and 1-bromo-3-methyl butane (0.715 mL, 5.96 mmol) in N,N-dimethylacetamide (20 mL) was heated at 65° C. for 5 days. The solution was cooled to about 25° C. and partitioned between 10% aqueous ammonium chloride and dichloromethane, the organic layer separated and concentrated under reduced pressure. The residue was chromatographed on silica gel, eluting with 1% methanol in dichloromethane to provide the title compound (0.569 g, 42%).
