Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A cooled (0° C.) solution of lithium hydroxide (0.048 g, 2.015 mmol) in water (20 ml) was stirred and treated with nitromethane (1.23 g, 20.15 mmol), 1,1,1-trifluoro-3-methylbutan-2-one (3.11 g, 22.17 mmol), cetyltrimethylammonium Chloride (0.871 g, 2.72 mmol) and MgSO4 (0.485 g, 4.03 mmol). The white suspension was stirred at 0° C. for 1 hr, then at RT for 2 days. The resulting biphasic mixture was separated and the more dense lower layer was collected and dissolved in diethyl ether (30 ml). The mixture was dried over MgSO4, filtered and concentrated in vacuo to give a pale yellow oil. The oil was taken up in diethyl ether (10 ml) and passed through a pre-packed SCX-2 cartridge eluting with 100% diethyl ether. The filtrate was concentrated in vacuo to afford the title compound as a colourless oil. 1H NMR (400 MHz, CDCl3): The white suspension was stirred at 0° C. for 1 hr The resulting biphasic mixture was separated the more dense lower layer was collected dissolved in diethyl ether (30 ml) The mixture was dried over MgSO4 filtered concentrated in vacuo to give a pale yellow oil eluting with 100% diethyl ether The filtrate was concentrated in vacuo
