Reaction Steps

To a stirred suspension of Boc-Beta-Ala-OH (40.0 g, 211 mmol) in DMF (200 ml) at 60° C. under N2 was added potassium carbonate (40.0 g, 289 mmol). To this mixture was added 2-chloro-N,N-dipropyl-acetamide (36.7 g, 207 mmol) in DMF (75 ml). The reaction mixture was allowed to stir at 60° C. overnight. The reaction was allowed to cool to RT and diluted with DCM (400 ml) followed by water (500 ml). The organic layer was separated and washed with brine (200 ml), dried over MgSO4 and concentrated in vacuo to yield a pale yellow oil. To the oil was added n-heptane (500 ml) (azeotrope for DMF) which was concentrated in vacuo to afford the title compound; LC-MS Rt 1.14 mins; 331.3 [M+H]+, Method 2minLC_v003.
