실험 절차

To a solution of 1-methyl-1H-pyrazol-3-amine (37.2 mg, 0.383 mmol) in DMF (0.8 mL) was added 60% NaH (14.10 mg, 0.353 mmol). The mixture was stirred for 10 min. Solid 8A (50 mg, 0.153 mmol) was added in one portion. The reaction mixture was stirred at room temperature for 3 h. Methanol (5 mL) was added and a solid precipitated that was collected by filtration and dried to give 18A (26 mg, 37%) as an off white solid. [M+H]=387. HPLC Peak Rt=2.753 minutes. (Chromolith column 4.6×50 mm eluting with 10-90% aqueous methanol over 4 minutes containing 0.1% TFA, 4 mL/min, monitoring at 254 nm.)
