Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 6279-86-3, name is Triethyl methanetricarboxylate, This compound has unique chemical properties. The synthetic route is as follows., 6279-86-3
1b) 6-Hydroxy-2-phenyl-3-(phenylmethyl)-4(3H)-pyrimidinone; A mixture of the compound from example 1(a) (0.342 g, 1.63 mmol), triethyl methanetricarboxylate (0.755 g, 3.25 mmol), methanolic sodium methoxide (0.378 mL of a 4.37 M solution, 1.65 mmol) and ethanol (3 mL) was stirred in a microwave reactor at 160 C. for 0.5 h, then cooled and poured into 1M aqueous hydrochloric acid (20 mL). The mixture was extracted with ethyl acetate, and the extracts washed with brine, dried (MgSO4) and evaporated under reduced pressure. The residue was chromatographed (silica gel, 5-10% methanol/dichloromethane) to give the title compound (0.320 g, 44%) as a foam. 1H NMR (400 MHz, DMSO-d6) delta ppm 5.05 (s, 2 H) 5.50 (s, 1 H) 6.87 (m, 2 H) 7.18-7.26 (m, 3 H) 7.36-7.43 (m,4H) 7.49 (m, 1 H) 11.64 (s, 1 H).
