Reaction Steps

A solution of 2-ethoxy-2-methylpropanoic acid (1.1 g, 8.32 mmol) in MeCN (15 mL) was treated with EDC (1.596 g, 8.32 mmol) and HOBT (1.275 g, 8.32 mmol), stirred at RT for 2 h, treated with NH4OH (˜15M, 1.7 mL, ˜25.5 mmol) and stirred at RT overnight. The mixture was treated with satd. NaHCO3 and water, extracted with EtOAc (5×) and the combined organics were dried over MgSO4 and concentrated to dryness to afford 2-ethoxy-2-methylpropanamide (1.1 g, 101%) as a solid. 1H NMR (400 MHz, DMSO-d6): δ 7.03 (s, 2H), 3.31 (q, J=7.0 Hz, 2H), 1.21 (s, 6H), 1.10 (t, J=7.0 Hz, 3H).
