4-(6-methoxynaphthalen-2-yl)butan-2-ol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred mixture of 2-hydroxy-4-(6-methoxy-2-naphthyl) butane (1.15 g:0.005 mole) in toluene (45 ml) containing dry pyridine (3 ml) was added 3,4,5-trimethoxy-benzoyl chloride, prepared from the corresponding acid (1.06 g:0.005 mole) and oxalyl chloride (1 ml). After standing for 48 hours at room temperature, the resulting mixture was added to water and extracted with ether. The organic extract was washed twice with water, dried (Na2SO4) and concentrated. The crude oil was chromatographed on alumina (100 g) using 10% ethereal hexane as eluant to afford the 3,4,5-trimethoxybenzoate of 2-hydroxy-4-(6-methoxy-2-naphthyl)butane as a pale yellow oil. extracted with ether The organic extract was washed twice with water dried (Na2SO4) concentrated The crude oil was chromatographed on alumina (100 g)
