Procedure
The addition of cyclopropyl magnesium bromide (2.8 mL, 0.5 M, 1.4 mmol) to 5-(3-cyano-benzyloxy)-4-formyl-6-methyl-pyridin-3-ylmethyl]-(4-cyano-phenyl)-carbamic acid tert-butyl ester (109) (474 mg, 0.9 mmol), was carried out as described in Example 104, gave [5-(3-cyano-benzyloxy)-4-(cyclopropyl-hydroxy-methyl)-6-methyl-pyridin-3-ylmethyl]-(4-cyano-phenyl)-carbamic acid tert-butyl ester (117) (293 mg, 57% yield).
