Tetrahydrofuran → HCID 69596297, compound

Participants

Reaction Steps

1-(2-Chloro-phenyl)-ethanol (31.4 mg, 0.20 mmol) was dissolved into 1.7 mL of anhydrous tetrahydrofuran and treated with sodium hydride (8.0 mg, 60% dispersion in mineral oil, 0.20 mmol). This was stirred under nitrogen for 1 hour at ambient temperature, then the reaction was treated with 4-(4-chloro-pyrimidin-2-yl)-piperazine-1-carboxylic acid tert-butyl ester (I-2a) (50 mg, 0.17 mmol) in one portion. The resultant mixture was refluxed under nitrogen for 4 hours. After cooling to room temperature, the reaction was poured into water (20 mL) and extracted with ethyl acetate (2×25 mL). The combined organic extracts were washed with brine (20 mL), then dried over sodium sulfate, filtered, and concentrated. The residue was purified by preparative TLC (7:13 ethyl acetate:hexanes) to afford 64.3 mg of the title product (I-2b).
