Reaction Steps

Et3N (1 drop, catalytic) was added to a stirred suspension of mono-Methyl isophthalate (0.294 mmol, 1.0 eq) in 2 ml SOCl2 under Ar. The mixture was heated to reflux at 90° C. for 2 h. The reaction was cooled to RT, and the solvent was removed in vacuo. The residue was placed under an Ar atmosphere and dissolved in 2 ml anh CH2Cl2. The resulting solution was treated with a solution of N-((4-methylthiazol-2-yl)methyl)propan-2-amine (0.294 mmol, 1.0 eq made from reductive amination of 4-methylthiazole-2-carbaldehyde with isopropylamine) dissolved in 1 ml anh CH2Cl2 under Ar. After stirring at RT for 30 min, the reaction was treated with ET3N (0.294 mmol, 1 eq). After stirring at RT for 30 min, the reaction is poured into a seperatory funnel, washed with sat. NaHCO3 (×1), water (×3), brine (×1), and dried over Na2SO4. The inorganics were removed via filtration, and the solvent was removed in vacuo yielding the crude product in 93% yield.
