Reaction Steps

To a solution of the crude toluene-4-sulfonic acid 1-cyano-cyclopentylmethyl ester in DMF (70 mL) was added 5-chloro-2-hydroxy-benzaldehyde (12.48 g, 80 mmol) and K2CO3 (13.25 g, 96 mmol). After heated at 100° C. for 3 h, the reaction mixture was poured into water. The solution was diluted with EtOAc (200 mL), washed with water, dried and concentrated to give the title compound as a yellow oil (17.4 g). The oil was used for next step reaction directly without further purification.
