실험 절차

Rac-cis-tert-butyl 4-[2-(2-iodoethyl)cyclopropyl]piperidine-1-carboxylate (86 mg, 0.23 mmol) from Step 3 of this example and 6-[(4-hydroxybenzyl)amino]-2-methylpyrimidine-4-carbonitrile (63.4 mg, 0.25 mmol) from Step 2 of this example were dissolved in DMF (2.3 mL), sodium hydride (18 mg, 0.45 mmol) was added. After 10 minutes, the reaction was quenched with saturated ammonia chloride solution (5 mL), extracted with ethyl acetate (10 mL), second washed with brine (5 mL). The organic phase was dried by magnesium sulfate, filtered, concentrated and purified by preparative-TLC (Analtech Silica Gel GF 1500 μM, 20×20 cm) using 30% ethyl acetate/hexane to give the title compound as a white solid.
