Reaction Steps

The amine (7.0 g, 23 mmol) from Example 102 and sodium carbonate (4.88 g, 46 mmol) were slurried in ethanol (50 ml). Benzyl bromide was added and the reaction was stirred for 18 hours at 25° C. The reaction was filtered and concentrated. The residue was partitioned between water and dichloromethane. The dichloromethane layer was dried (MgSO4), filtered, and concentrated to yield a crude yellow residue which was chromatographed on a silica gel column eluted initially with dichloromethane followed by methanol/dichloromethane (1:99). The title compound was eluted as a pale yellow oil (7.2 g, 88%).
