Procedure

To a 0° C. solution of 3-chloroaniline (4.33 mL, 40.9 mmol), the product from Step K (ca. 41 mmol), and crushed 4 Å molecular sieves (10 g) in dichloroethane (100 mL) under nitrogen was added sodium triacetoxyborohydride (12.9 g, 61.5 mmol). The reaction was stirred for one hour, then warmed to room temperature. After 3 hours, the solution was poured into EtOAc and washed with water, sat. NaHCO3 soln. and brine. The solution was dried over sodium sulfate and concentrated in vacuo to provide the crude product.
