Draw the organic intermediate of the reaction scheme and choose the appropriate reagents to perform the transformations. The starting material is a 4 carbon chain where carbon 1 is double bonded to oxygen and single bonded to chloride. This reacts with reagent 1 to form an intermediate. The intermediate reacts with reagent 2 to form the product. The product is a 4 carbon chain where carbon 1 has a hydroxy and phenyl ring substituent. Identify reagent 1.
