Procedure

2,6-di-t-butylphenol, 20.6 g, in 100 ml of stirred methanol containing 16.2 g of 37% aqueous formaldehyde (excess) was treated with a freshly prepared solution of 5.6 g of potassium hydroxide and 8.9 g of 2-nitropropane and heated under nitrogen for 21/2 hours. Upon cooling, 19.8 g of product, mp 101°-4° C., was obtained in two crops. Recrystallization from methanol afforded product melting 103.5°-105.5° C.
