82% | With trichlorophosphate In toluene for 3 h; Reflux | POCl3 (0.460 g, 3.0 mmol) was added to the solution of compound 13 (1.0 mmol) in 15 mL of toluene and the mixture was stirred at reflux for 3 hours. Redundant POCl3 was removed under reduced pressure and ice water (10mL) was added. The solution was adjusted to the pH 9-10 with sodium carbonate and then extracted with methyl tert-butyl ether (MTBE). The organic phase was dried over sodium sulfate, and the solvent was removed under reduced pressure to afford compound 14. (Yield: 82percent) MS (ESI) (m /z) [M+H]+ 143.1. |
71% | With ammonia In sodium chloride; dichloromethane; trichlorophosphate | Part 1 Preparation of 2,4-dimethyl-6-chloropyrimidine. METHOD: 20 g (16.1*10-2 mol) of 2,4-dimethyl-6-hydroxypyrimidine in suspension in 150 ml of phosphorus oxychloride are introduced into a 250 ml three-necked flask fitted with a thermometer, a condenser and a magnetic stirrer. The mixture is heated at 90° C. for one and a half hours. The mixture is then cooled and then evaporated to dryness. The residue which crystallises at ambient temperature is added, in small portions, to a binary mixture consisting of dichloromethane (200 ml) and 10percent ammonia (300 ml), previously cooled to -5° C. in an ice bath containing sodium chloride. The mixture is stirred cold for half an hour and the organic phase is then decanted off, washed with water until neutral and then dried over sodium sulphate, filtered and evaporated. The yellow liquid obtained is filtered through a glass frit filled with silica using the dichloromethane/methanol (99/1) eluent system; the pure fractions collected are evaporated. 16.4 g of a colourless liquid which has a persistent odour and which crystallises in a refrigerator are obtained. Yield: 71percent. Elementary analysis for C6 H7 ClN2; molecular weight=142.5. The 1 H and 13 C NMR and mass spectra are in accordance with the expected structure. |
