(1-chloro-2-methylpropyl) benzoate

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

実験手順: Following general procedure A, methyl hydrogen fumarate (0.50 g, 3.82 mmol) was reacted with CsHCO3 (5.76 mmol) and chloroisobutyl benzoate (1.1 g, 5.17 mmol) at ca. 55° C. to afford 0.18 g (15% yield) of the title compound (46) after purification by silica gel flash chromatography (Biotage) using a mixture of ethyl acetate (EtOAc) and hexanes (1:7). 1H NMR (CDCl3, 400 MHz): δ 8.04-8.01 (m, 2H), 7.58-7.55 (m, 1H), 7.45-7.41 (m, 2H) 6.98 (d, J=4.8 Hz, 1H), 6.90 (d, J=16.0 Hz, 1H), 6.84 (d, J=16.0 Hz, 1H), 3.78 (s, 3H), 2.25-2.21 (m, 1H), 1.10-1.07 (m, 6H); MS (ESI): m/z 307.11 (M+H)+.
