Reaction Steps

A solution containing the product from Example 36C (0.107 g, 0.396 mmol) in dichloromethane (2 mL) at 0° C. was treated with 6-methyl-2-pyridinemethanol (0.053 g, 0.435 mmol), triphenylphosphine (0.135 g, 0.515 mmol), followed by diethyl azodicarboxylate (0.080 mL, 0.515 mmol), stirred at 25° C. for 16 hours. Water (2 mL) was added and the reaction was stirred for 2 hours at 25° C. The reaction mixture was partitioned between dichloromethane and water, and the organic phase was washed with brine and dried over MgSO4, filtered and concentrated. The residue was chromatographed on silica gel eluting with 0-30% ethyl acetate/dichloromethane to give the title compound (0.154 g, 94% yield).
