Versuchsvorschrift

Sodium cyanoborohydride (0.75 g, 11.9 mmol) was added portionwise to (S)—N1-methyl-N1-(2-oxoethyl)-N3-(4-(piperidin-1-yl)-2-(4-(1,2,3,4-tetrahydronaphthalen-1-ylcarbamoyl)pyridin-2-yl)phenyl)isophthalamide 187a (1.5 g, 2.38 mmol), N-methyl-2,5,8,11,14,17,20-heptaoxadocosan-22-amine 135c.1 (2.52 g, 7.14 mmol) and acetic acid (0.41 mL, 7.14 mmol) in ethanol (15 mL) and the mixture stirred overnight at room temperature. The reaction was diluted with ethyl acetate, washed with saturated aqueous sodium bicarbonate and brine, dried (MgSO4). The residue was purified by PTLC (10% MeOH/20% ethyl acetate/dichloromethane) to give product as an orange oil (0.85 g, 37%); MS (ES, m/z): 969 [M+H]+; NMR (400 MHz, CDCl3, ppm): δ 12.8 (s, 1H); 8.80 (s, 1H); 8.55 (d, J=8.8 Hz, 1H); 8.10 (s, 1H); 7.98-8.02 (m, 2H); 7.47-7.55 (m, 3H); 7.06-7.24 (m, 5H); 6.69 (m, 1H); 5.41 (m, 1H).
