Reaction Steps

This was prepared in an identical manner to the compound described in Example 1 using 2-hydroxy-2-phenylethanamine (0.51 g) and 4-{2-carboethoxy-2-methylethenyl}phenylpropan-2-one (1.0 g). The title compound was isolated as an oil (1.4 g). The oil was dissolved in methanol and treated with fumaric acid (0.43 g) in methanol. Evaporation of the solvent gave an oil which was triturated with ethyl acetate and recrystallized from ethyl acetate to give the title compound hemifumarate (0.38 g) as a 50:50 mixture of diastereoisomers m.p. 135°-138° C. τ(CDCl3) 8.8 (3H, d, J=6 Hz), 8.7 (3H, t, J=7 Hz) 8.0 (3H, s), 6.35-7.5 (7H, m, 2H disappears with D2O), 5.8 (2H, q, J=7 Hz) 4.85 (1H, m), 3.15 (1H, s), 2.8 (9H, m), 2.47 (1H, s), 1.8 (2H, broad, disappears with D2O).
