| [00134] L-Alanine isopropyl ester hydrochloride (21.82 g, 0.1303 mol) was charged under nitrogen atmosphere into a round bottom flask, tert-butyl methyl ether (98 mL) was added and the mixture was cooled to 0 °C. Dichlorophenylphosphate (26.2 g, 0.124 mol) was added. The reaction solution was cooled to -10 °C to 0 °C and triethylamine (38.38 mL, 0.248 mol) in tert-butyl methyl ether (98 mL) was added at - 10 °C to 0 °C. The reaction mixture was allowed to stir at 0 °C for 4 h. [00135] In a separate round bottom flask, a 3,5-diiodo-4-hydroxy methylbenzoate (DIHMB - 30 g, 0.074 mol) and tert-butyl methyl ether (98 mL) mixture was prepared under nitrogen atmosphere. This mixture was cooled to -5 to 0 °C and triethylamine (17.42 mL, 0.124 mol) was added. This solution was added to the previous reaction mixture at 0 to 5 °C under nitrogen atmosphere and stirred for 1 to 2 h at 0 °C. After stirring for 2 h, water (66 mL) was added and the organic layer was twice washed with 2.5percent Na2C03 (aq) solution (66 mL), followed by 6percent NaHCC (aq) solution (500 mL). The organic layer was concentrated under vacuum to give a solid residue (60 g). This solid was stirred in hexanes (85 mL) and filtered. The obtained solid was dried at 35 °C under vacuum to give the desired product as an off-white solid (43.49 g, 80percent yield; >90percent purity) as 1 : 1 mixture of diastereomers. |
