53% | EXAMPLE 24 A solution of phenylmagnesium bromide (1M in THF, 4.2 mL, 4.2 mmol) is added to a solution of 4-chloro-2-methylthio-pyrimidine (296 mg, 1.84 mmol) and Fe(acac)3 (32 mg, 0.09 mmol) in THF (10 mL) at -30 C. After stirring for 50 min at that temperature, the reaction is quenched with brine, the aqueous layer is extracted with Et2O, the combined organic phases are dried over Na2SO4 and evaporated, and the residue is purified by flash chromatography (hexane/ethyl acetate, 10:1). After eluding a first fraction containing biphenyl (90 mg), one obtains 2-methylthio-4-phenyl-pyrimidine as a pale yellow solid (197 mg, 53%). 1H NMR (300 MHz, CD2Cl2) delta8.53 (d, 1H), 8.09-8.13 (m, 2H), 7.53-7.48 (m, 3H), 7.39 (d, 2H), 2.63 (s, 3H); 13C NMR (75 MHz, CD2Cl2) delta173.0, 164.0, 158.0, 136.7, 131.1, 131.0, 129.2, 127.5, 127.4, 112.2, 14.3. |

In N,N-dimethyl-formamide; | EXAMPLE 9 This Example illustrates the preparation of (E)-methyl 2-[2-(4-phenylpyrimidin-2-yloxy)phenyl]-3-methoxypropenoate (Compound No.180 of Table III). To a stirred suspension of sodium methanethiolate (0.35 g) in DMF (5 ml) at 0 C. was added dropwise a solution of 2-chloro-4-phenylpyrimidine (0.86 g, prepared from 2-chloropyrimidine according to the method of D B Harden et al., J.Org.Chem., 1988, 53, 4137) in DMF (5 ml). Stirring was continued at 0 C. for 15 minutes and then the temperature was allowed to rise to room temperature. After a further 2 hours, the reaction mixture was diluted with water and then extracted with ether (*3). The combined ether extracts were washed with water, dried, filtered and evaporated to give 2-methylthio-4-phenylpyrimidine (0.76 g) as a brown solid which was used directly in the next stage. |

With 3-chloro-benzenecarboperoxoic acid; In dichloromethane; | To a solution of <strong>[56734-10-2]2-methylthio-4-phenylpyrimidine</strong> (0.76 g) in dichloromethane (15 ml) at 0 C. was added portionwise over 15 minutes meta-chloroperbenzoic acid (1.65 g). The resulting white emulsion was warmed to room temperature and stirred for a further 3% hours. The reaction mixture was evaporated to give a white solid. The solid was redissolved in dichloromethane and washed with saturated aqueous sodium bicarbonate solution (*2), and then with water (*2). The resulting solution was dried, filtered and evaporated to give crude 2-methanesulphonyl-4-phenylpyrimidine (0.84 g) as a yellowish solid which was used in the next stage without further purification. | |
In hexane; dichloromethane; 3-chloro-benzenecarboperoxoic acid; | EXAMPLE 68 2-Methylsulfonyl-4-phenylpyrimidine A solution of 2.02 g. of <strong>[56734-10-2]2-methylthio-4-phenylpyrimidine</strong> in 50 ml. of methylene chloride is cooled in an ice bath with 4.33 g. of m-chloroperbenzoic acid being added portionwise. After standing at room temperature overnight, the reaction mixture is washed with a saturated potassium carbonate solution, separated, and dried over anhydrous sodium sulfate. The solution is passed through a short pad of hydrous magnesium silicate absorbent and the eluent is refluxed on a steam bath with addition of hexane until crystallization is induced. On cooling the desired compound is removed by filtration, m.p. 135.5-137 C. Rec. Trav. Chim. 93, 375 (1974), m.p. 135-135.5 C. |

In sodium hydroxide; | EXAMPLE 66 2-Methylthio-4-phenylpyrimidine A solution of 3.5 g. of 2-mercapto-4-phenylpyrimidine in 50 ml. of 1 N sodium hydroxide is cooled to near 0 C. and 2.94 g. of methyl iodide is added. After stirring at room temperature for 2 hours, the product is recovered by filtration. Recrystallization from methylene chloride-hexane affords the desired compound, m.p. 87-89 C. |
