Participants

Reaction Steps

2-Methyloxy-5-nitrophenol (14.27 g, 84.4 mmol) was dissolved in dry dimethylformamide (80 ml). Cyclopentylbromide (176 g, 127 ml, 118.2 mmol) and cesium carbonate (38.5 g, 118.2 mmol) were added and the suspension stirred overnight at room temperature. The mixture was poured into saturated Na2CO3 (200 ml) and extracted with ethyl acetate (700 ml). The organic layer was washed with saturated Na2CO3 until no yellow colour was detected. The organic layer was then dried (MgSO4) and concentrated in vacuo to give the title Compound as a yellow solid (15.0 g).
