Reaction Steps

Charge 4-chloro-5-iodo-7H-pyrrolo[2,3-]pyrimidine (5.0 g, 1.0 eq), 2-methyl-3-butyn-2-ol (9.02 g, 6.0 eq), TEA (1.68 g, 0.93 eq), CuI (1.36 g, 0.4 eq), DMF (62.5 mL) and THF (187.5 mL) at RT under argon atmosphere. Stir the reaction mass at RT under argon atmosphere for 5 min. Charge Pd(PPh3)4 (1.03 g, 0.05 eq) and stir the reaction mass at 45° C. for 16 h. Monitor the reaction by TLC (65% CHCl3: 23% Hexane: 12% Acetone). Concentrate the reaction mass under vacuum. Charge ethyl acetate and give washing with water and saturated aq. sodium chloride. Dry the organic layer over anhydrous Na2SO4 and concentrate it under vacuum. Crystallize the compound in 65% CHCl3: 23% hexane: 12% Acetone to give the desired compound (3.35 g, 79.7%).
