A mixture of HATU (0.086 g, 0.225 mmol) and 1-oxo-2,3,4,5-tetrahydro-1H-[1,4]diazepino[1,2-a]indole-8-carboxylic acid (Intermediate J, 0.050 g, 0.205 mmol) in dichlorethane (1 mL) in a microwave vial is heated in a microwave reactor at 60° C. for 60 minutes. Polystyrene bound 2-tert-butylimino-1,3-dimethylperhydro-1,3,2-diazaphosphorine (0.307 g, 0.615 mmol) and 3-trifluoromethyl-isoxazol-5-ylamine (0.094 g, 0.615 mmol) are added to the mixture and the vial is heated in a microwave at 120° C. for an additional 60 minutes. The resin is filtered off and washed several times with DMF. After the removal of solvent, the residue is purified by flash column chromatography using 5% methanol/dichlorormethane to afford title compound (0.012 g, 15.5%) as a white solid.
