The mixture was cooled to −60° C. and treated with T3P (propyl phosphonic anhydride; 0.50 mL, 1.2 eq.) and DIPEA (0.24 mL, 2.0 eq.) and stirred for 1 h. The progress of the reaction was followed by TLC analysis using 10% MeOH:CH2Cl2 as mobile phase and visualizing under UV light. The reaction mixture was then poured into water (50 mL) and extracted with CH2Cl2 (2×50 mL). The combined organic layers were washed with brine (50 mL), dried over anhydrous MgSO4, filtered, and concentrated under reduced pressure (25° C., 20 mmHg) to afford crude compound which was purified by column chromatography (SiO2, 60/120 mesh, MeOH:CH2Cl2 as mobile phase). The desired compound started eluting in 3.0% MeOH:CH2Cl2. The fractions containing the compound were collected and concentrated under reduced pressure to afford 140 mg (yield: 43%) (Z)-3-(3-(3,5-bis(trifluoromethyl)phenyl)-1H-1,2,4-triazol-1-yl)-N′-methyl-N′-(pyridin-3-yl)acrylohydrazide. 1H NMR (400 MHz, DMSO-d6) δ, 10.55 (s, 1H), 9.41 (s, 1H), 9.15 (s, 2H), 8.58 (s, 1H), 8.53 (s, 1H), 8.29 (s, 1H), 7.51-7.54 (d, J=10.4 Hz, 1H), 7.18-7.22 (m, 2H), 6.05-6.07 (d, J=10.4 Hz, 1H), 3.20 (s, 3H); LCMS for C19H15F6N6O [M+H]+ 457.35; found 457.19 (RT 2.43 min, purity: 83.48%).

After 5 minutes, the solution became homogenous and was allowed to stir for an additional 30 minutes. The reaction mixture was then concentrated in vacuo to afford (2,2-Dimethyl-[1,3]dioxolan-4-yl)-ethanol (7.72 g, 96.7%).

Procedure:
9.6 g (0.03 mol) of the N-hydroxysuccinimide ester of N-benzyloxycarbonyl-L-alanine and 5.26 g (0.03 mol) of dimethyl aminomethylphosphonate hydrochloride were stirred in 65 ml of dry dimethylformamide. While stirring and maintaining the temperature below 20° C, there were added dropwise 4.2 ml of dry triethylamine. The mixture was then stirred overnight at room temperature. The triethylamine hydrochloride was filtered off and washed with a little dimethylformamide. The filtrate was evaporated under an oil-pump vacuum and at a bath temperature below 40° C. The residual oil was treated with 40 ml of water and the resulting mixture extracted with four 40 ml portions of chloroform. The combined organic phases were washed with a small volume of a strong potassium carbonate solution and then dried over sodium sulphate. The sodium sulphate was filtered off and the filtrate evaporated first under a water-pump vacuum and then under an oil-pump vacuum. There were obtained 11.0 g of dimethyl [(N-benzyloxycarbonyl-L-alanyl)amino]-methylphosphonate as an oil with the expected N.M.R. spectrum.

Procedure:
Methylacetoacetate (1.63 mL, 15.1 mmol) was dissolved in dry THF (42 mL) and cooled to 0° C. NaH (60% in mineral oil, 0.604 g, 15.1 mmol) were carefully added and the reaction mixture was stirred for 20 min. A solution of BuLi in hexanes (1.6 M, 9.44 mL, 15.1 mmol) was added dropwise and the resulting mixture was stirred an additional 20 min. A solution of 3-(2,4-dimethoxyphenyl)-1-cyclopentylpropan-1-one (2.33 g, 7.55 mmol) from Step 4 above in THF (37 mL) was added dropwise. After stirring 1 h, the reaction mixture was quenched with saturated aq NH4Cl (100 mL) and extracted with Et2O (600 mL). The organic phase was dried over MgSO4 and evaporated. The residue was then stirred overnight in a mixture of 0.1 M NaOH (370 mL) and THF (37 mL). After the addition of solution of 10% aqueous KHSO4 (50 mL), the resulting mixture was stirred 30 min and then extracted with Et2O (600 mL). The organic phase was washed with brine, dried over MgSO4 and evaporated. The residue was purified by flash column chromatography (50% EtOAc in hexanes) to give the product (1.54 g, 52%) as a white foam. 1H NMR (CDCl3) δ 1.43 (m, 2 H), 1.78 (m, 8 H), 2.33 (m, 1H), 2.58 (m, 2H), 2.78 (s, 2H), 3.43 (s, 2H), 3.78 (s, 6H), 6.37 (s, 1H), 6.47 (s, 1H), 6.93 (d, J=7.93 Hz, 1H).
