Procedure

4'-Methylbiphenyl-2-carboxylic acid (50.0 g, 0.24 mmol) was converted into the corresponding acid chloride as described in Example 89, Part B using thionyl chloride. This acid chloride was subsequently reacted with 3-aminopropionitrile fumarate (30.25 g, 0.24 mmol) under Schotten-Baumann reaction conditions described in Example 209, Part B to yield 53.50 g of white powder after recrystallization from methylcyclohexane/butylchloride; m.p. 102.0°-103.5° C.; NMR (200 MHz, CDCl3): δ7.68 (d, 1H, J=7 Hz); 7.56-7.19 (m, 7H); 5.65 (bm, 1H); 3.43 (d of t, 2H, J=7,7 Hz); 2.39 (t, 2H, J=7 Hz). Anal. calcd. for C17H16N2O: C, 77.25; H, 6.10; N, 10.60. Found: C, 77.42; H, 6.40; N, 10.68.
