Procedure
Methyl chloroformate (0.072 mL, 0.925 mmol) is added dropwise at 0° C. to to the crude amine hydrochloride prepared in Step 1 of Example 15 (0.316 g, 0.881 mmol) in a mixture of pyridine (4 mL) and dichloromethane (4 mL). The mixture is allowed to warm to room temperature, stirred for 1 hour, and then evaporated to dryness. The residue is purified by PTLC (10% methanol/dichloromethane) to give white solid (0.26 g, 78%). M.p. 196-7° C.
