Procedure

To tert-butyl 3-((2R)-2-(2,9,9-trimethyl-3,5-dioxa-4-bora-tricyclo[6.1.1.02,6]dec-4-yl)-2-(isoindoline-5-carboxamido)ethyl)-2-methoxybenzoate from Example 9 step 2 (240 mg, 0.42 mmol) in 1,2-dichloroethane (5 mL) was added nicotinaldehyde (90 mg, 0.84 mmol) and Na(OAc)3BH4 (211 mg, 1 mmol). The reaction mixture was stirred at room temperature for 6 hr. Water (10 mL) was added at 0° C. and the aqueous phase was extracted with EtOAc. The organic phase was washed brine, dried over Na2SO4 and concentrated in vacuo. The crude product was carried to the next step without further purification. ESI-MS m/z 666.1 (MH)+.
