Intermediate 45: Step a (2,4-Dimethylthiazol-5-yl)(1-methyl-1H-1,2,3-triazol-5-yl)methanol To a flask containing 1-methyl-1H-1,2,3-triazole (1.60 g, 19.3 mmol, Intermediate 42, step a) was added THF (200 mL) and the solution was cooled to -40 C. To this colorless homogeneous solution was added n-BuLi (2.5 M in hexanes, 7.7 mL, 19.2 mmol) dropwise which immediately afforded a dark brown viscous mixture. The mixture was kept between -10 to -20 C. for 60 min, then 2,4-dimethylthiazole-5-carbaldehyde (3.03 g, 21.5 mmol) in THF (5 mL) was introduced and the reaction mixture began to stir much more easily, but still remained brownish. Once the aldehyde was added the reaction was placed in an ice-bath and maintained there until it warmed to room temp. After 3 hours the reaction was quenched by pouring into a saturated solution of NH4Cl at room temperature. The aqueous portion was extracted with EtOAc (5*100 mL). The combined organics were washed with brine, dried over MgSO4, filtered and concentrated to give a brown oil-foam. Flash chromatography on silica gel (10-30% acetone increasing gradient to 10% MeOH-DCM) gave the title compound as a light orange foam.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 16681-65-5
