Procedure

A mixture of 55 mg (0.135 mmol) of (S)-1-(2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-9-yl)pyrrolidine-2-carboxylic acid, N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (57.0 mg, 0.150 mmol), N,N-Diisopropylethylamine (52.2 uL, 0.300 mmol) and Ammonium chloride (8.02 mg, 0.150 mmol) in N,N-Dimethylacetamide (3.0 mL, 32 mmol) was stirred for 1 hour. The mixture was concentrated in vacuum, the residue triturated with water, 0.01 N aq HCL, water, dried in vacuum and subjected to RP HPLC and then chiral purification to give 375. Yield 12 mg.
