-Butyl 3-ethynyibenzoate (117) (1.603 g, 7.93 mmol), 4-iodo-2-(methylthio)-5- (trifiuoromethyl)pyrimidine (114) (1.647 g, 5.15 mmol), PdCI2(PPh3)2 (0.316 g, 0.45 mmoi), PPh3 (0.355 g, 1.35 mmol), Cu(i)i (0.232 g, 1.22 mmol) and trethyiamine (4.00 mL, 28.7 mmoi) were combined in D F (20 mL) and the resulting mixture heated at 120 C under microwave irradiation for 25 minutes. The mixture was then concentrated under reduced pressure and purified twice using silica gel column chromatography (10-20% EtOAc/petroleum benzine 40-60 C then 50-100% DCM/petroleum benzine 40-60 C) to give the title compound (118) (0.624 g, 31 %) as a yellow solid; 1H NMR (400 MHz, CDCI3) delta 8.73 (d, J = 0,8 Hz, H), 8.25 (m, H), 8.08 (m, 1 H), 7.78 (m, 1 H), 7.48 (m, 1 H), 2.63 (s, 3H), 1.61 (s, 9H).

According to the analysis of related databases, 914943-91-2, the application of this compound in the production field has become more and more popular.
