Embodiment 1

[0480] (N,N-Diethylcarbamoyl)methylmethyl(2E)but-2-ene-1,4-dioate (1)

[0481]

[0482] According to General Procedure A, methyl hydrogen fumarate (MHF) (0.39 g, 3.00 mmol) dissolved in NMP was mixed with 2-chloro-N,N-diethylacetamide (0.44 g, 3.00 mmol) at about 55 °C ) in CsHCO 3 (0.69 g, 3.60 mmol) gave 0.37 g ( 51% yield) of the title compound (1). M.p.: 53-56°C. 1 H NMR (CDCl 3 , 400MHz): δ6.99-6.90(m, 2H), 4.83(s, 2H), 3.80(s, 3H), 3.39(q, J=7.2Hz, 2H), 3.26(q, J=7.2Hz, 2H), 1.24(t, J=7.2Hz, 3H), 1.14(t, J=7.2Hz, 3H). MS(ESI):m / z244.13(M+H) + .

Embodiment 2

[0484] Methyl[N-benzylcarbamoyl]methyl(2E)but-2-ene-1,4-dioate (2)

[0485]

[0486] According to General Procedure A, methyl hydrogen fumarate (MHF) (0.50 g, 3.85 mmol) dissolved in NMP was mixed with N-benzylchloroacetamide (0.84 g, 4.61 mmol) in CsHCO at about 55 °C. 3 Reaction in the presence of (0.89 g, 4.61 mmol) afforded 0.56 g (53% yield) of the title compound (2) as a white solid after purification by mass-directed preparative HPLC and lyophilization. 1 H NMR (CDCl 3 , 400MHz): δ7.36-7.26(m, 5H), 6.94-6.88(m, 2H), 6.19(br s, 1H), 4.73(s, 2H), 4.51(d, J=5.6Hz, 2H) , 3.81(s, 3H). MS(ESI): m / z 278.04(M+H) + .
