71% With 3-[(ethylimino)methylene]-amino}-N,N,N-trimethyl-1-propanaminium iodide; benzotriazol-1-ol; N-ethyl-N,N-diisopropylamine; In dichloromethane; at 20℃; for 24h;Product distribution / selectivity; Preparation 1 To a RT solution of <strong>[499-49-0]5-methylisophthalic acid</strong> (6.68 g, 37.1 mmol) and DIEA (19.7 ml, 14.4 g, 111 mmol) in CH2CI2 (74 ml) were added SEQUENTIALLY DI-N-PROPYL- amine (5.1 MI, 3.75 g, 37.1 mmol), HOBt (5.01 g, 37.1 mmol) in two portions, and EDCI (7.11 g, 37.1 mmol) in four portions. The reaction mixture was stirred for 24 h, then diluted with 1 N HCI. The mixture was stirred vigorously for 15 min, and the copious solid that precipitated was removed by filtration. The filtrate was diluted with water, and the aqueous phase was adjusted to PH-1. The phases were separated and the aqueous layer extracted twice with CH2CI2. The combined organics were dried (MGS04), filtered, and concentrated. This crude residue was purified by column chromatography (silica, 0No.100percent EtOAc/hexanes) to give a semi-solid that was further recrystallized from 15percent EtOAc/hexanes to give the product (4.5 g). Additional product (2.4 g) was obtained by a second column chromatography of the crystallization mother liquor. These two samples were combined (6.9 g total mass, 26.2 mmol, 71 percent). LCMS (Conditions A): TR = 3.9 min; (M+H) + = 264.
40% 5-Methylisophtalic acid (100-150 mg, 0.55-0.83 mmol) was dissolved in DMF (3 niL), cooled to 0 0C and DIPEA (1 equiv) was added and the mixture was stirred until a clear solution was achieved. PyBOP (1 equiv) was added, and the stirring was continued for 30 min at 0 0C. A solution of amine (dipropylamine, butylmethylamine and i?-(methoxymethyl)pyrrolidine for A- 17, A-18 and A-19 respectively, 1.1 equiv) and DIPEA (1 equiv) in DMF (3 mL) was added dropwise to the activated ester solution and the reaction was stirred for 1 h. Et2O (30 mL) was added followed by 1 M NaOH (10 mL) and the phases were separated. The organic layer was extracted with 2 X 10 mL 1 M NaOH. The combined aqueous phases were acidified to pH 1 with 3 M HCl and extracted with 3 X 10 mL DCM. The combined organic layers were concentrated in vacuo and the product was purified by gradient column chromatography (1 :1 hexanes/ EtOAc - EtOAc with 1percent AcOH throughout. This gave the title compounds with some minor contaminants and the products were used as such without further purification. A-17: 40percent, m/z ES+ 264.2 [M+H]+; A-18: 38percent m/z ES+ 250.2 [M+H]+; A-19: 42percent, m/z ES+ 278.2 [M+H]+.

84% With 1,8-diazabicyclo[5.4.0]undec-7-ene; In N,N-dimethyl-formamide; tert-butyl alcohol; 3,5-Dicarboxybenzyl Methanethiosulfonate (1c). 1,1'-Carbonyldiimidazole (6.67 g, 0.0411 mol) was added to a solution of <strong>[499-49-0]toluene-3,5-dicarboxylic acid</strong> (2) (3.364 g, 0.0187 mol) in DMF (30 mL) and the resulting mixture stirred at 40° C. under N2. After 1.5 h DBU (6.15 mIL, 0.041 mol) and t-BuOH (7.7 mL, 0.0822 mol) were added. After 24 h the solution was cooled, ether (150 mL) added and the mixture acidified (HCl (aq.), 1.5 M). The ethereal layer was separated and the aqueous layer further extracted (ether, 150 mL). The organic fractions were combined, washed with water and 10percent K2CO3 (aq.), dried (MgSO4), filtered and the solvent removed. The residue was purified by flash chromatography (EtOAc:hexane, 1:50) to afford a colorless oil which solidified upon standing to give di-tert-butyl toluene-3,5-dicarboxylate (4.58 g, 84percent) as a white solid; mp 86.5-87.5° C.
