Procedure

To a solution of 3-[(2-chloro-5-methyl-4-pyrimidinyl)(methyl)amino]-1-propanol (Example 341, 785 mg, 3.64 mmol) and ethyl [(1S)-5-hydroxy-2,3-dihydro-1H-inden-1-yl]acetate (Example 6, 401 mg, 1.82 mmol) in THF (17 mL) were added PPh3 (954 mg, 3.64 mmol) and ADDP (918 mg, 3.64 mmol). The reaction mixture was vigorously stirred at rt for 24 h after which additional PPh3 (954 mg, 3.64 mmol) and ADDP (918 mg, 3.64 mmol) were added. After an additional 24 h, the reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel chromatography (3:1 hexanes/EtOAc) to give the product (586 mg, 77%) as a colorless oil. 1H NMR (400 MHz, CDCl3) δ 1.26 (t, 3H), 1.71-1.76 (m, 1H), 2.06-2.11 (m, 2H), 2.26 (s, 3H), 2.34-2.42 (m, 2H), 2.67-2.88 (m, 3H), 3.15 (s, 3H), 3.49-3.50 (m, 1H), 3.70 (t, 2H), 3.94 (t, 2H), 4.13 (q, 2H), 6.64 (d, 1H), 6.70 (s, 1H), 7.02 (d, 1H), 7.75 (s, 1H).
