Procedure
2-((1H-indol-3-yl)thio)acetic acid (650 mg, 3.14 mmol) from Step B, 3-amino-5-methyl-isoxazole (616 mg, 6.28 mmol), PyClu (2.00 g, 6.28 mmol), and DIEA (1.36 mL, 7.85 mmol) were added to dichloroethane (25 mL) and microwave irradiated at 110° C. for 20 minutes. The solvent was removed in vacuo and the remaining residue purified on a silica gel column (0-70% ethyl acetate:hexanes over 33 min) to yield the desired product (642 mg, 2.23 mmol, 71% yield). LCMS>99% at 214 nm, RT=1.23 min, m/z=288 (M+1).
