Procedure:
A mixture of 40 g 3,5-dimethyl-4-hydroxybenzonitrile, 30.77 g 1-chloro-4-pentyne, 74.63 g potassium carbonate and 130 ml N-methylpyrrolidinone was heated with stirring to 100° C. and stirring was continued at 100° C. for 4 hrs. The mixture was cooled to room temperature and 800 ml of water was added. This mixture was extracted with 400 ml ethyl acetate and the extract was washed with 2N sodium hydroxide and saturated sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated in vacuo. The resulting black oil, dissolved in ethyl acetate, was passed through a pad of florisil to remove the color and the filtrate was concentrated in vacuo. The residue was recrystallized from methyl alcohol to yield 34.64 g (60.2%) of 3,5-dimethyl-4-(3-ethynylpropoxy)benzonitrile, m.p. 48°-49° C.

Procedure:
To a solution of 5-[(tert-butyldimethylsilyl)oxy]-1H-indazole (13 g, 52.34 mmol, 1.00 equiv) in N,N-dimethylformamide (550 mL) maintained under nitrogen was added NIS (28.6 g, 104.76 mmol, 2.00 equiv) in portions.

Procedure:
To a cooled (0° C.) solution of 2-allyloxyethylbenzene (5. g; 30.8 mmol) dissolved in THF (75 ml) is slowly added a 0.5M THF solution of 9-BBN [9-borabicyclo [3.3.1]nonane] (68 ml; 34 mmol) and the reaction mixture warmed to room temperature and stirred for 4 hours. The reaction mixture is then cooled to 0° C. and 5 ml H2O is added followed by slow addition of 6N NaOH (30 ml; 7.2 g/30 ml). After stirring for 5 minutes, 30% H2O2 (20 ml) is added over 15 min. The reaction mixture warms significantly but is kept from refluxing. After addition is complete, it is stirred for 15 minutes allowing the mixture to come to room temperature. It is then diluted with Et2O, washed with H2O 2x, Na2S2O3 2x, NaHCO3 and brine, dried (MgSO4) and concentrated to dryness. The residue is purified by column chromatography using Et2O to obtain 3-(2-phenylethoxy)-1-propanol which is used directly in Step C.
