Synthesis of DHT heptanoate can be done by acylation of the 17beta-hydroxyl group of DHT. weigh 25g of DHT and disolve in dichloromethane (250 mL). add 16ml Heptanoyl chloride add together with 4-(N,N-dimethylamino)pyridine (3.75 g) as a catalyst. stopper flask with an anhydrous calcium chloride tube, protect apparatus from light,it is a vampire, stir magneticaly at reg interval. After few days the reaction mixture can be was washed with sodiumhydroxide (2 x 75 mL, 1 mol/L), hydrochloric acid (2 x 75 mL, 1 mol/L), and then deionized water until aqueous layer of neutral pH is obtained. Evaporation of the organic layer should resulted in a yellow, waxy solid(hmmmm..sounds like the test and nandrolone esters everyone is ordering from china) that can be further dried (might take a while,,eat a chicken breast while you wait). recrystallize with the use of acetone/water and check by electron impact full-scan MS with an ion-trap detector , coupled to a gas chromatograph fitted with a methyl silicone capillary column (3). Purity of the compound can be also assessed by NMR ,
i dont claim to be original in my synthesis of DHT heptanoate, tetrahydrogestrinone(bary bonds favorite), oxandrolone, or 2,17 dimethyl dht(superdrol).pending on patent rights claimed by various pharmaceutical companies in northern NJ or around the world.
