YieldReaction ConditionsOperation in experiment
97% With triethanolamine; hydrogen sulfide In ethanol 2.a Example 2; Step a To a SOLUTION/SUSPENSION of 1 (10. 0 g; 72 mmol) in ethanol (100 mL) was added TRIETHANOLAMINE (4.0 mL; 39. 8 mmol). H2S was then passed through the solution. After a few minutes precipitation of a yellow solid was observed. The reaction was continued until TLC showed complete conversion (30 min). The reaction mixture was poured into ice-water (-300 mL), which resulted in precipitation of product. After stirring for 15 min the solid was filtered off, washed with water and dried (vacuum, P205). YIELD : 12. 1 g (97%).

YieldReaction ConditionsOperation in experiment
With triethylamine 7 Compounds in example 7 may be prepared in a similar manner as those described in Example 5: the thioamide of 2-chloroisonicotinamide [prepared according to Libermann, D ; Rist, N.; Grumbach, F.; Cals, S.; Moyeux, M.; Rouaix, A. Memoires Presentes a la Societe Chimique 1958, 694-702] is alkylated with methyl iodide. The resulting thioimidate salt (4.3 g, 13.5 mmol) is stirred overnight in 100 ml isopropanol with 1.7 g ammonium acetate. After concentration and trituration with isopropanol/t-BuOMe, filtration provides the amidine as a solid (2.3 g). This material is stirred overnight with 3.5 g solid NaHCO3, 2.4 ml of a 50% aqueous solution of H2NCN, 40 ml isopropanol, and 1100 ml H2O. The resulting precipitate is triturated with a small amount of isopropanol to obtain 1.6 g cyanoamidine 1170. This material is suspended in CH2Cl2/CH3CN with 1.3 ml POCl3 and 1 ml DMF at 0° C. and the mixture is warmed to room temperature. After several hours, the homogenous solution is poured into a 1:1 mixture of pH 7 buffer and saturated NaHCO3. After extraction with EtOAc and filtration through a plug of silica, 1.6 g of 2-chloro-4-(2-chloro-pyridin-4-yl)-[1,3,5]triazine 1171 is obtained as a white solid. MS m/z=227 [M+H]+; HPLC Rt=13.18 min.

The reaction mixture was heated at 100 °C for 8 h and then allowed to cool and then quenched with distilled water (30 mL). The organic materials were extracted with ethyl acetate (30 mL). The organic layer was isolated and dried over anhydrous Na2SO4. Solvent was evaporated under reduced pressure. The solid residue was purified by silica gel flash chromatography, using ethyl acetate-hexane (1:1), and then dichloromethane-methanol (95:5) to yield a yellowish-white solid (64 mg, 67%): mp 182-183 °C. 1H NMR (DMSO-d6) δ 9.28 (s, 1H), 8.56 (m, 3H), 8.42 (d, J = 7.2 Hz, 1H), 8.10 (s, 1H), 8.01 (d, J = 7.0 Hz, 1H), 7.52 (dd, J = 3.9, 7.2 Hz, 1H); 13C NMR (DMSO-d6) δ 164.22, 154.03, 152.41, 152.06, 150.36, 148.35, 143.52, 134.50, 130.11, 124.88, 121.19, 120.72, 120.06; ESIMS (m/z, rel intensity) 274/276 (MH+, 100/24); HRMS (ESI), m/z MH+ 274.0201, calcd for C13H8ClN3S 274.0206; HPLC purity (C-18 reverse phase column): 98.93% (methanol-H2O, 95:5).
