반응 단계
3-(Benzothiazol-6-ylamino)-2-methyl-propionic acid (I-167a: 500 mg, 2.118 mmol) was refluxed with triethylamine (1 mL, 6.989 mmol), DPPA (1.75 g, 6.35 mmol) and toluene (10 mL) at 120° C. in a sealed tube to afford the crude product. The reaction was monitored by TLC (5% methanol in chloroform). Purification by column chromatography on silica gel (2% methanol in chloroform) afforded 350 mg of the product (71.42% yield).
