Reaction Conditions

Reaction Steps

To LiOH (0.193 g, 8.06 mmol) in a 3-neck roundbottom flask was added water (25 ml), nitromethane (3.76 ml, 81 mmol) and trifluoroacetone (7.95 ml, 89 mmol). Cetyltrimethylammonium chloride (3.8 g, 10.88 mmol) and MgSO4 (1.9 g, 16.12 mmol) were added and the resulting yellow solution stirred at 20-25° C. for 2 days. The reaction mixture was poured into diethyl ether (120 ml) and washed with water (3×200 ml) and brine (1×100 ml). The organic portion was dried over MgSO4 and concentrated in vacuo to afford the title compound as a yellow liquid. 1H NMR (CDCl3, 400 MHz): δ 4.7 (1H d), δ 4.5 (1H, d), δ 3.7 (1H, broad), δ 1.6 (3H, s).
