YieldReaction ConditionsOperation in experiment
57% With potassium carbonate; In acetonitrile; at 20℃; for 0.5h; To a solution of intermediate B (150mg, 0.76mmol) in MeCN (0.7ml) was added K2CO3. To this, a solution of intermediate A (174mg, 0.76mmol) in MeCN (0.7ml) was added dropwise resulting in a white suspension. Stirring at r.t. was continued for 30 EPO <DP n="80"/>min after which the white suspension turned pale yellow. The reaction mixture was evaporated, re dissolved in EtOAc (10ml) and washed with water (5ml). The EtOAc layer was dried (Na2SO4) filtered and concentrated to dryness. Purification by flash chromatography (100% DCM to 2% MeOH/DCM) gave the title compound as an off- white solid (0.15g, 57%). LCMS purity 89%, m/z 349 [M+H]+.

The reaction mixture was stirred for 10 min at room temperature and the solvent was evaporated. The remaining solid was dissolved in dichloromethane, the solution was washed with saturated aqueous NaHCO3 and brine, dried over MgSO4, filtered and concentrated in vacuo to afford the title compound 150 as a yellow solid (416 mg, 90% yield). 1H NMR: (DMSO) delta (ppm): 8.76 (s, 2H), 4.26 (q, J=7.1 Hz, 2H), 3.70-3.53 (m, 4H), 3.26 (dd, J=11.3, 3.9 Hz, 1H), 2.07-1.98 (m, 1H), 1.75-1.67 (m, 3H), 1.29 (t, J=7.0 Hz, 3H).

YieldReaction ConditionsOperation in experiment
57% General procedure: 60% Sodium hydride (w/w) in mineral oil (0.0015 mol) was added to a mixture of appropriate III (0.001 mol) in THF (15 ml) under the condition of inert atmosphere using N2 flow at 5C. The reaction mixture was kept for 1 h at room temperature. A solution of 2-(methylsulfonyl)-5-pyrimidinecarboxylic acid, ethyl ester (0.0015 mol) in THF (15 ml) was slowly added to reaction mixture. The resulting reaction mixture was stirred for 2-3 h at 5C. The distilled water (20 ml) was added. The reaction mixture was extracted (10 ml x 3) with dichloromethane. The separated organic layer was dried over MgSO4, filtered, and the solvent was evaporated under reduced pressure to obtain crude product, recrytallized by ethyl acetate.
