Ethyl Bromide → HCID 68115357, compound

Participants

Reaction Steps

To a 25-mL round-bottom flask was added a solution of intermediate 18.3 (125 mg, 0.28 mmol, 1.00 equiv) in distilled DMF (10 mL) followed by sodium hydride (60% dispersion in mineral oil, 96 mg, 2.80 mmol) at 0° C. and the reaction mixture was stirred for 30 min. Then bromoethane (305 mg, 2.80 mmol) was added and the resulting solution was stirred overnight at room temperature. The reaction was then quenched with water and extracted with 100 mL of ethyl acetate. The organic layer was washed with brine and dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was loaded onto a silica gel column with EtOAc/petroleum ether (1:5). Purification afforded tert-butyl N-(4-[[3-(2-ethoxyethyl)-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)-N-methylcarbamate (19.1, 19 mg, 14%) as a colorless oil.
