Reaction Steps

To the solution of 4-[4-(7-Methoxy-6-methyl-indan-4-ylmethyl)-3,5-dimethyl-pyrazol-1-yl]-3-oxo-butyric acid ethyl ester (1.0 gm, 0.0025 mole) in Ethanol (60 ml), Acetamidine hydrochloride (0.71 gm, 0.0075 mole) was added. Further to this, Sodium ethoxide (0.51 gm, 0.0075 mole) was added at 5-10° C. and then stirred at 70-75° C. for 2 hours. The Ethanol was distilled under vacuum and residue was partitioned between Ethyl acetate (100 ml) and water (100 ml). Further aqueous layer was extracted with Ethyl acetate (2×100 ml). The combined volume of Ethyl acetate layer was reduced to 20 ml and then filtered to give 800 mg of desired product.
