Reaction Steps

A solution of 6-(cyclohexyl-cyclopropylmethyl-amino)-pyrimidine-4-carboxylic acid (Intermediate 13, 1.00 g; 3.63 mmol) in dry DMF (100 ml) was treated with polymer-supported Mukaiyama reagent, prepared as described in “S. Crosignani et al. Org. Lett. 2004, 6(24), 4579-4582” (2987 mg; 6.54 mmol), 4-aminobenzyl alcohol (Fluka, 492 mg; 3.99 mmol) and triethylamine (1.52 ml; 10.9 mmol). The reaction mixture was then stirred at room temperature for 18 hours. DCM was added and the product was filtered through an SPE column (Isolute NH2, 10g) and the column washed with DCM. The mixture was concentrated then rediluted in EtOAc. The organic phase was washed 5 times with brine, dried over MgSO4 and the solvent removed under vacuum to give the title compound (990 mg, 72%).
