YieldReaction ConditionsOperation in experiment
91% for 4 h; Heating / reflux 4-Chloro-3-iodobenzonitrile (60f). A mixture of aldoxime 59 (5.65 g, 20.0 mmol) in acetic anhydride (10 mL) was refluxed for 4 h. The reaction mixture was poured into ice-water and stirred for 1 h. The product was filtered off as a light yellow solid (4.79 g, 91percent): mp 91-93 °C; 1H NMR δ 8.49 (d, J = 2.2 Hz, 1H), 7.90 (dd, J = 8.2 and 2.2 Hz, 1H), 7.79 (d, J = 8.2 Hz, 1H); HPLC (Method B) tR 6.24 min (91.75 area percent at 254 nm).

K2CO3/DME; (I) Cs2CO3, aq. CH3CN or MeOH; (m) NaH, toluene.; A second general method is depicted in Scheme 2 immediately hereinabove and comprises the cycloaddition of cyanophenylacetylenes 51 and benzaldehyde chlorooximes 52 in the presence of bis(tributyltin) oxide, see Moriya, O., et al., J. Chem. Soc., Perkin Trans., 1, 413-417 (1994); Moriya, O., et al., J. Chem. Soc., Chem. Commun., 17-18 (1991), or triethylamine, see Thomsen, l., et al., Acta Chem. Scand. (B), 319-313 (1988), in nonpolar solvents to give isoxazole dinitriles 53a-h,k-s and bromonitrile 53i. The latter was treated with copper(I) cyanide to give dinitrile 53j. See Friedman. L., et al., J. Org. Chem., 26, 2522-2524 (1961). This method also afforded alternate routes to dinitriles 50a,b,g, k prepared by the first method as provided in Scheme 1. The phenylacetylene synthons 51a-g were prepared as shown in Scheme 3 below. Starting materials 60a,e,g were commercially available. Nitration of 60a gave 60b. See Borsche, W., L., et al., Chem. Ber., 49, 2222-2243 (1916). The latter was reduced to aniline 56, see Blanksma, J. J., et al., Recl. Trav. Chim. Pays-Bas, 66, 365-373 (1947), which underwent diazotization followed by treatment with copper(l) chloride to give chlorobenzene 60c. Triflate 60d was prepared by treatment of 4-bromo-3-hydroxybenzonitrile with triflic anhydride. The preparation of aryl iodide 60f began with the known transformation of aldehyde 57 to iodo derivative 58. See Lulinski, P., et al., Bull. Chem. Soc. Jpn., 73(4), 951-956 (2000). Treatment of 58 with hydroxylamine hydrochloride gave aldoxime 59, which was dehydrated to give nitrile 60f using acetic anhydride. The aryl halides or triflates 60a-g were treated with (trimethylsilyl)acetylene, see Roesch. K. R., et al., J. Org. Chem., 66, 412-420 (2001), or with 2-methyl-3-butyn-2-ol, see Bleicher, L. S., et al., J. Org. Chem., 63, 1109-1118 (1998), to give intermediates 61a-f or 62a-f, respectively, of which 61a,d and 62a have been reported previously. See Dirk. S. M., et al., Tetrahedron, 59(3), 287-293 (2003); Bleicher, L. S., et al., J. Org. Chem., 63, 1109-1118 (1998). The acetylenes 51 (of which 51a,e were known previously), see Blackburn, B. K., et al., J. Med. Chem., 40(5), 717-729 (1997); Dulog, L., et al., Liebigs Ann. Chem., 9, 1663-1671 (1995), were obtained by the treatment of intermediates 61 or 62 with cesium carbonate in acetonitrile or sodium hydride in toluene, respectively. See Bleicher, L. S., et al., J. Org. Chem., 63, 1109-1118 (1998). The use of cesium carbonate in acetonitrile was introduced for the deprotection of intermediates 61 after the treatment of compound 61b with potassium carbonate in methanol, see Blackburn, B. K., et al., J. Med. Chem., 40(5), 717-729 (1997), failed to give product 51b. The pathway using 2-methyl-3-butyn-2-ol provided more economical preparations of all phenylacetylenes 51 except nitro analog 51b.
