91% | With thionyl chloride In methanol at 70℃; for 2 h; | To a 250 mL round bottom flask was added 3-(4-bromophenyl)propanoic acid 147a (5g, 21.83 mmol, 1.00 equiv.) and methanol (50 mL). Thionyl chloride (7.76 g, 65.23 mmol,5 3.00 equiv.) vva;;; added dropwise with stirring. The resulting mixture was stirred at 70 °C for2h. The reaction was quenched by the addition of water/ice. The aqueous mixture wasextracted with ethyl acetate (200 mL x 3), and the combined organic extracts were washedwith brine (100 mL x 2), dried over anhydrous sodium sulfate and concentrated. The residuewas purified by silica gel column chromatography eluting with PE:EA (5.2percent) to give methyl10 3-(4-bromophenyl)propanoate l47b (4.84 g, 91 ~"0) as a colorless oil |

100% | With Novozym 435; acylase I from Aspergillus melleus; amano lipase AK from pseudomonas fluorescens; lipase from wheat germ; papaine In toluene at 40℃; for 48 h; Enzymatic reaction | General procedure: To the solution of acid (1 mmol) in toluene (1 ml), the corresponding dialkyl carbonate (2 mmol) and enzymes (per 4 mg of each enzyme) were added in 5 ml vial. The reaction mixture was stirring for 24 or 48 h at 40 °C in vortex mixture (Heidolph Promax 1020) equipped with incubator (Heidolph Inkubator 1000). After cooling, the mixture was washed with NaHCO3 (3×) and brine (1×). Organic solvent was removed under vacuum to obtain the product 2a–2r. |

99% | for 16 h; Reflux | General procedure: In distinct reactors, solutions of the appropriate 3-(3-bromophenyl)-propionic acid or 3-(4-Bromophenyl)-propionic acid in MeOH were prepared and concentrated H2SO4 was added to each reactor. The resulting mixtures were stirred under reflux for 16h. Each crude mixture was reduced under vacuo and the residues were partitioned with dichloromethane (20 mL) and saturated NaHCO3 solution (20 mL). The organic layers of each reaction was dried with Na2SO4, filtered and evaporated. The resulting compounds were used in a further reaction without any further purification. |

90% | With sulfuric acid In water for 18 h; Reflux; Inert atmosphere | General procedure: A stirred solution of the appropriate bromophenyl alkanoic acid(1 eq) in MeOH (25 mL)was treated with H2SO4 (0.1 eq of a conc. aq.solution) and heated at reflux for 18 h. The resultant solution wascooled to room temperature and concentrated under reducedpressure. The resultant oil was diluted with NaHCO3 (50 mL of a sat.aq. solution) and subsequently extracted with diethyl ether(3 25 mL). The combined organics were washed with brine(1 100 mL), dried (MgSO4), filtered and concentrated underreduced pressure to give the desired methyl ester: |
