Reference of 104566-41-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 104566-41-8 as follows.
Another procedure involves use amide formation using the acid chloride as shown in the following reaction. To 4-biphenylacetic acid (2.5 g) in a flask, thionylchloride (20 ml) was added and heated to reflux for 1 h, cooled, and the excess thionylchloride removed under vacuum to dryness, then the produced crude acid chloride 2.8 g, dissolved in dry DCM (dichloromethane) (30 ml), and added drop wise at 0 C. to equimolar amount of the 3-benzyloxybenzylamine solution in DCM (10 ml) with (1.5 mol) of triethylamine (TEA) and stirred for 5 hrs, then poured onto acidified cold water, the organic layer washed with water, brine and the solvent removed under reduced pressure to give the target amide in 80% yield. 1H NMR (DMSO, 500 MHz): delta 8.58 (t, J=12 Hz 1H), 7.60-7.57 (m, 4H), 7.44-7.29(m, 10H), delta 7.21(t, J=16.5 Hz, 2H), 6.85(d, J=6.5 Hz, 2H), 6.81(d, J=8.0 Hz, 1H), 5.00(s, 2H), 4.24(d, J=6 Hz, 2H), 3.51(s, 2H).
