Procedure
Following general procedure A, methyl hydrogen fumarate (1.00 g, 7.68 mmol) was reacted with CsHCO3 (2.22 g, 11.52 mmol) and chlorobutyl cyclohexanecarboxylate (2.16 g, 9.98 mmol) at ca. 55° C. to afford 1.2 g (50% yield) of the title compound (44) as a clear oil after purification by mass-guided preparatory. HPLC and lyophilization. 1H NMR (CDCl3, 400 MHz): δ 6.90-6.77 (m, 3H), 3.81 (s, 3H), 2.34-2.28 (m, 1H), 1.91-1.88 (m, 2H), 1.82-1.73 (m, 4H), 1.65-1.62 (m, 2H), 1.47-1.39 (m, 4H), 1.29-1.23 (m, 2H), 0.98-0.94 (t, 3H). MS (ESI): m/z 313.09 (M+H)+.
