YieldReaction ConditionsOperation in experiment
91% With trichlorophosphate at 45℃; for 0.633333h; Sonication; Green chemistry; General procedures for the synthesisof compounds 7a-7c, 8a-8c, and 9a-9c General procedure: Ultrasonication methodA mixture of 4, 5, or 6 (1.0 mmol), arylsulfonylacetic acid(1.0 mmol), and 3 cm3 phosphorus oxychloride was subjectedto ultrasound irradiation at a frequency of 35 kHzfor 30-50 min at 45 C. After completion of the reaction,the excess phosphorus oxychloride was removed under reduced pressure and the residue was poured onto crushedice. The separated solid was collected by filtration. It waswashed with saturated sodium bicarbonate solution followedby water, dried, and purified by column chromatography(silica gel 60-120 mesh) using ethyl acetatehexane(1:3) as eluent.2-[5-(Furan-2-yl)-1H-pyrazol-3-yl]-5-(tosylmethyl)-1,3,4-oxadiazole(7a, C17H14N4O4S) White solid (0.33 g, 91%);m.p.: 176-178 C; 1H NMR (DMSO-d6): d = 2.55 (s, 3H,Ar-CH3), 4.15 (s, 2H, CH2), 6.69-8.07 (m, 8H, Ar-H),11.74 (bs, 1H, pyrazole-NH) ppm; 13C NMR (DMSO-d6):d = 21.4 (Ar-CH3), 59.1 (CH2), 104.2, 107.8, 114.3, 126.8,131.2, 132.3, 134.3, 138.4, 141.5, 145.7, 156.8, 160.6,162.5 ppm; IR (KBr): m = 1145, 1334 (SO2), 1565 (C=N),1600 (C=C), 3242 (NH) cm-1; HRMS: m/z = 393.3736([M?Na]+).
