Procedure

Triethylamine (27.89 mL, 200 mmol) was added to a mixture of the compound of Example b (2.47 g, 10 mmol) and N-propyl-N-iso-propylamine hydrochloride (~92 mmol) in toluene (100 mL). The reaction was stirred overnight at ambient temperature, then was partitioned between ethyl acetate and dilute citric acid. The organic phase was washed with brine, dried (MgSO4), and concentrated to afford 2.50 g of the title compound as a waxy amber solid, an 80% yield.
