Reaction Steps

To a solution of the crude 2-cyano-4-(spiro[2.5]oct-6-ylmethyl)pyrimidine-5-carboxylic acid (22 mg, step 74.5) in DMF (1.5 mL) are added (R)-2-phenyl-1-pyrrolidin-1-ylmethylethylamine (0.083 mmol), EDCl—H2O (0.11 mmol), and HOAt (0.11 mmol) at room temperature. The reaction mixture is stirred for 24 h and the reaction is quenched by the addition of H2O. The mixture is extracted with AcOEt, and the organic extracts are dried over Na2SO4, filtered, and concentrated in vacuo. The resulting residue is purified by RP-HPLC to give the title compound; MS (M+1)+: 474, Rf (solvent): 0.63 (CH2Cl2:MeOH=10:1).
