Procedimiento

N-[(4aR,7aS)-7a-(3-Aminophenyl)-6-(5-fluoropyrimidin-2-yl)-4,4a,5,7-tetrahydropyrrolo[3,4-d][1,3]thiazin-2-yl]benzamide (0.30 g, 0.67 mmol) is dissolved in dichloromethane (10 mL) and 5-cyanopyridine-2-carboxylic acid (129 mg, 0.87 mmol), 1-hydroxybenzotriazole (185 mg, 1.34 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (169 mg, 0.87 mmol) are added. Diisopropylethyamine (0.35 mL, 2 mmol) is added and the reaction is stirred at room temperature overnight. The material is purified directly with silica gel chromatography eluting with a 0-100% ethyl acetate/hexanes gradient to give the title compound (360 mg, 88%). ES/MS (m/e): 579 (M+H).
