Procedure
A solution of HATU (221 mg, 0.55 mmol) in DMA (10 mL) was added to a mixture of the 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]-3-methoxy-benzoic acid (Example 242; 220 mg, 0.5 mmol), DIPEA (261 uL, 1.5 mmol) and 4-amino-3-methoxy-N-(1-methyl-4-piperidyl)benzamide (WO06/018220; 72 mg, 0.62 mmol) in DMA (10 mL). The resulting mixture was stirred at room temperature for 2 hours, then partially purified by SCX. The compound was retrieved 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 the title compound as a pale yellow amorphous solid. (154 mg, 58%)
