Procedure
A solution of HATU (126 mg, 0.33 mmol) in DMA (5 mL) was added to a mixture of 4-[(2-cyclopentyl-4,4,6-trimethyl-5-oxo-2,6,9,11-tetrazabicyclo[5.4.0]undeca-7,9,11-trien-10-yl)amino]benzoic acid, (Intermediate 129; 123 mg, 0.3 mmol) DIPEA (261 uL, 1.5 mmol) and 4-amino N-methylpiperidine (43 mg, 0.375) in DMA (5 mL). The resulting mixture was stirred at room temperature for 2 hours, then partially purified by SCX. The compound was eluted from the SCX column using 7N ammonia in methanol, then concentrated in vacuo, and further purified by column chromatography, eluting with 0-10% ammonia (7N in methanol) in DCM. The pure material was recovered as an orange oil, which foamed and solidified under high vacuum. Trituration under ether gave a pale yellow amorphous solid. (100 mg, 66%)
