Procedure

A solution of EXAMPLE 415B (145 mg) and N-ethyl-N-isopropylpropan-2-amine (120 μl) in anhydrous dichloromethane (5 mL) and N,N-dimethylformamide (2 mL) was cooled with an ice bath and acetic anhydride (56 μl) was added dropwise. The mixture was stirred at room temperature for 3 hours and concentrated to dryness. The residue was triturated with water. The resulting solid was dried under vacuum to give the title compound.
