Participants

Reaction Steps

The starting material can be obtained, for example, analogously to Example 1b): The reaction of 2.0 g of 2'-cyanobiphenyl-4-carbaldehyde, 9.6 g of molecular sieve 5 A, 1.34 g of (L)-norvaline methyl ester hydrochloride and 680 mg of sodium cyanoborohydride yields N-[(2'-cyanobiphenyl-4-yl)methyl]-(L)-norvaline methyl ester after flash chromatography (N3). 1H-NMR (DMSO): 0.83 ppm (t, 3H), 1.33 ppm (m, 2H), 1.55 ppm (m, 2H), 3.62 ppm (s, 3H), 3.1 ppm (m, 1H), 7.3-8 ppm aromatics.
