Stage 1 – Coupling; Piperidin-4yl-methanol (2.48g, 21.55mmol) was stirred in 1 :1 DMF/MeCN (2OmL) with K2CO3 (8.9g, 64.65mmol) for 10 minutes at RT under a nitrogen atmosphere. Intermediate F (5g, 21.55mmol) was then added and the reaction allowed to stir for 20 minutes. It was then diluted with H2O (10OmL) and extracted with EtOAc (2 x 10OmL). The combined organic layers were dried (MgSO4) and the solvent removed in vacuo to give the product as an orange solid which was used in the next step without further purification (5.7Og, 99percent). m/z = 266 [M+H]+.

General procedure: 60percent 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 5°C. 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 5°C. 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.

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 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 (100percent DCM to 2percent MeOH/DCM) gave the title compound as an off- white solid (0.15g, 57percent). LCMS purity 89percent, m/z 349 [M+H]+.
