Procedure

To a cold (0° C.) solution of tert-butyl 2-amino-4-({2-[(tert-butoxycarbonyl)amino]ethyl}amino)-6-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]phenyl}-nicotinate (0.113 g, 0.178 mmol) in THF (5 mL) was added a solution of Vitride® (3.4 M, 1.0 mL, 3.4 mmol). The mixture was stirred at 0° C. for 0.5 hrs, quenched with saturated aqueous potassium sodium tartaric acid solution, and then partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to give a solid, which was triturated with ethyl acetate and diisopropyl ether to give tert-butyl 2-{[2-amino-6-{2-(cyclopropylmethoxy)-6-[(4-methoxybenzyl)oxy]-phenyl}-3-(hydroxymethyl)-4-pyridinyl]amino}ethylcarbamate as a pink solid (0.078 g, yield; 78%).
