What is the reaction equation for this: Place 0.75 g of 3-nitroacetophenone, 10 mL of absolute ethanol, and a magnetic stir bar in an Ts 19, 50 mL round bottom flask (rbf). Equip the flask with a condenser, begin stirring, then warm the solution in an oil bath heated to 90 °C until a solution is obtained. Cool the solution to room temperature then remove the condenser: a fine suspension of solid may form. Stir the suspension at room temperature while adding in 0.28 g of sodium borohydride. Stir then add 7.5 mL of water. Remove the flask from the heat source, cautiously add 0.5 mL (~10 drops) 3M HCl (aq) dropwise with stirring, and cool the reaction solution for 10 minutes in an ice-water bath to produce a suspension of the product.
